1 - Hell no, no dev will forget about 4 million users when there are only 11million 360s. A port costs 10% of dev costs, Ps3 user base is a increase of 36% numbers favor games staying 360/PS3
360 lost heavy Rain, and Ps3 gained timed exclusives in Haze and URT3 (so not all doom and gloom)

3 Seeing as best PS3 sellers are exclusives, id keep making games and using the hardware to the best it can do. If sales were low id go multi.
4 seriously doubt it, MS image has taken a bit hit these days, PS3 line up is to strong to overlook same goes for the far better hardware quality. PS3 heavy hitters will cause former PS2 owners to buy lots of PS3.
