The sheer lack of knowledge in this topic astounds me. I don't post here but I read this topic and was pretty taken aback by people's lack of knowledge on this topic. So I guess I'll fill some people in.
AoS was in Starcraft. I'd imagine AoS2 will be in SC2, and whether people here want to admit it or not, it's the SAME THING AS DOTA, but with different heroes and items.
No AOS is not even close to the same thing as DOTA. AOS was players against a computer. It was a one-team game. You "won" the map similar to the hero-defense maps that exist on warcraft 3 right now. The only similarities were the spawned units going against each other and killing the other team's main. Anybody who says otherwise has no idea what Aeon of Strife is and obviously didn't play the original.
Next to the morons expecting IceFrog to simply port DOTA to SC2:
NOT HAPPENING. Sure any SC2 map IceFrog makes will have SOME sort of cult following because of his popularity due to his work on DOTA: Allstars. However, the guy is already tied up enough in his work on Warcraft, there's simply no way he could mod Warcraft, play Starcraft 2 and then find the time to create and update a Starcraft 2 mod of DOTA's magnitude without changing his priorities greatly. And this comes from someone who knows absolutely nothing about Icefrog's real life.
Lastly, the people in this topic who don't know the SC2 editor's capabilities should definitely read this paragraph. Items, experience and level-up capabilities will all be included in the Editor. The only thing that remains to be seen is whether or not hero attributes will be incorporated into the in-game interface (Strength, Agility, Intelligence in WC3) and if so, whether or not they'd be customizable.
Simply because the fantasy theme of DOTA on Warcraft doesn't necessarily "fit in" to the Starcraft universe does not mean a great AOS map cannot be made. The power of this new editor remains to be seen, but the Data editor will give the freedom to create any spell someone wants from scratch without having to "base it off another spell" so to speak. Furthermore the ability to define syntax and libraries within the editor and increased functionality of the User-Interface portion of the trigger editor will make it much easier to create maps with wide varieties of functionality and spells or abilities.
So AOS =/= DOTA despite it being credited for inspiring Eul to create DOTA, Icefrog won't port DOTA to SC2, and yes the editor/universe for SC2 are powerful enough to create amazingly vast and diverse AOS maps.
