Dodece: PS3 shipped 1.1 million consoles and 360 shipped 1.2 million worldwide. So there is only 0.1 million in shipped figures at least. These are from official quarterly from MS and Sony so you can't get much better figures. And official figures are the only really trustworthy figures, every other source only have estimates.
Let's speak the truth... The installation base difference is too insignificant to really make much difference. So most HD titles are going to remain multiplatform until the end of the generation. There is bigger chance that developers would forget both PS3 and 360 than just PS3.
