I was looking at all of the pictures and movies that they have, and I noticed something. Very few buildings besides terrain are shown. And then only 4 (maybe) terran units were shown, (siege tank, marine, scv, and possibly a firebat). Many protoss units were shown, but only 3 buildings that I could see, out of all of their screens, and only lings were shown insofar as zerg is concerned. A friend told me that there were some obvious texture flaws in some of the units shown (I know nothing about 3D art). So there is another setback. I also noticed that only two terrains were shown, the jungle area and the space platform. Being multiplayer playable with all three races doesn't mean that they have the textures finished, or even the models. I have played some beta rts games where most of the units were basically identical blocks, with only statistical differences. I would be hesitant to put a release date of less than a year and a half for this, based on what is shown from the site. If they show that they have made more progress (reveal other buildings or units in pictures) than I might think it could be released earlier. As it stands, it seems unreasonable to expect it to be out in 6 months.
