- Blizzard released a new WC3 patch this year
After how many years of nothing official, including new downloadable official maps ?
I believe no other gaming company has ever provided support for their retail game(s) over such a long period of time
- We know for sure at least one more patch is on its way
Has already officially been advertised as being mainly a balance patch. But they will of course never fix the already known issues they themselves listed, isn't it ?
Also, "Some tasks have extended production schedules", to quote the OP. Some things are already carefully planned for the next years imho
- An increased map limit size is on its way
OP says *perhaps* 150 MB. Why is nobody puzzled by this tentative 150 MB value ? 16 - 32 - 64 - 128 - 256... OK... but 150 does not "fit" imho. Sure, 150 comes close to 32+128. Does that lead us to something ?
- game now uses D3D9
Please document yourself on D3D9 features. Also, why was it a *silent* upgrade from D3D8 ?
- game now uses VC++ 2013
Please document yourself on anything related to VC++ 2013, how it interacts positively with modern CPUs / OSes, and other things
- planned integration with Bnet 2.0
Because all these efforts are of course one-time efforts
- Blizzard is currently updating his classic games
Yep, they decided that one morning, for they had nothing better to do that day. Tip : think *global* strategy here
atm there are 2 patches for DII, 1 for WC3, SC still pending. Again, how does that compare to other game companies ?

- There are more than a dozen employees working on the Classic titles
Of course, they will fire them right after a one-time patching session ? Formation and training is so overrated these days, especially when related to costs... [/sarcasm]
- I understand Robert Bridenbecker and Pete Stilwell are onboard

- Clásico is paying much attention to the posts from Blizzard's gamers community
http://us.battle.net/en/search?f=post&a=Clásico&sort=time
- Clásico officially stated they would like to take care of bots for the long-term, and emphasized their fondness for the games

(there are other posts like this from them)
Now of course fighting bots (and hacking) a an international level, is done by a one-time quick fix at the snap of fingers
- Code is being reviewed, some ASM has already been removed
Where to start with that one ? Sanitization, less dead code, less surface attack for exploits, more documented code, more portability on other game platforms, more modern programing fit for today's computers. All done with the objective of "not breaking shit". Again, just snapping fingers and yay ?
Plus, it is a new team which has to understand code done by other programers in the last century. First development of the game began in 1998, and it was first envisioned as a different kind of game. There was a change in directions in 2000 (which explains some of the mess modders are facing nowadays imho). Quoting OP, "Sorting through the code sounded a bit like archaeology"
- There were some issues related to maps in the last patch
And nobody wondered *why* ? Hint : think SC patch 1.12
- Blizzard released last year some redone WC3 assets
http://eu.battle.net//arcade/en/blog/17796669
Which of course will remain for SC2 only ? Absolutely unrelated to the *silent* switch to D3D9, of course...
- There is some demand, from the standard casual gamer, for so-called "HD". Meaning in fact something visually a bit more appealing, and a bit more on par with modern times
Please see above
- Blizzard has changed ; it is not the Blizzard from the 90's/2000's
Blizzard became more mod-friendly last year with SC2 (starter edition allows to play some mods afaik)
- Blizzard only met Kam and PurgeandFire since then ?
use a search engine
- Blizzard is very attentive to the feedback from fan communities
" Blizzard is reading the Hive and other fan sites, and are interested in a continued feedback loop. ". Think constructive synergy for mutual benefit here. How about the other game companies ?
- The general trend is leaning to nostalgia
See remade classics in widescreen / better resolution, from other games companies. There is money to be made here.
- The standalone PC Desktop is dead
yep. Think tablets, and also new ways of buying and gaming (and sometimes buying while gaming)
- Commercial games are about money
Captain Obvious speaking 
If a change in the game can be both benefic and financially beneficial to Blizzard, they will implement it in a later patch (shock ! horror !)
- A Warcraft movie is coming
Will lead to exposure of some of Blizzard's brand of products, towards the general mass-market consumer. The whole games had to be fixed first for compatibility, because of deadlines.
Also, a movie is about buying toys and stuff. Care for a ThrallMobile ?
Also, a commercial success may help Blizzard succeed where Square Pictures failed. Need I say more ?
