Well at least they have given themselves a chance. As others have said early game is far too cumbersome and boring. A push back gives them a chance to fix this. That doesn't mean they will - but this is the first step that was needed.
We know they aren't making Generals 2 - but if there is one thing they absolutely need to copy from Generals it is the pace of the game. The beta build that we all played was no where near that pace. Hopefully this push back is about steering the game back into that mold.
I think this is a smart move by Eugen, it at least acknowledges that they may have missed the mark in the first iteration of the game. Whether they have correctly identified the problem remains to be seen, but step 1 as they say is admission.
