the delay is only like a month. And the game's release isn't until 2010. One of the things that is included in the "Polish" is AI... back on the 24th I asked boogiebac if the 25th was still 'go' and he said the AI was not working yet, so no alpha until we had an enemy to play against. (where 'we' means those lucky enough to be in the alpha)
Besides, the removal of the 3D map has nothing to do with how "done" they are... it is to force users to look at the core-gameplay rather than wine about stuff like graphics (see the demigod beta)
