An excuse I would buy would be that trying to make games the same on three systems is hard enough, since same specs do not change the fact that they are working on three different systems at once. It's like building three different houses where you can't even reuse materials.
A flashy-first game is awesome when it comes out. A great-first game is awesome forever.
