I don't think its a matter of specs, but a matter of familiarity and development difficulty.
The PS3 is clearly the harder and less common architecture. Therefore instead of building on the 360 and then trying to port to PS3, which has routinely proven to have PS3's games that are flat out worse than their 360 versions. They will build it on the PS3 to ensure the game runs really well there and then port over to the 360 which will give them a much smoother transition since they are far more familiar with the system.
Makes perfect sense to me.
EDIT: Plus, EA recently stated that 2008 will be PS3 > 360, so they are shifting their resources to match their expectations.
