This is clearly SE looking to test waters and MS looking for more evidence that their consoles will be receive big franchises. Coming this late, on the least preferred console in the region, on multiple disks and with (unless they've improved things) a lower resolution both for gameplay and the cutscenes, I really wouldn't expect this to sell very much.
TBH, like Mass Effect 2, and other titles, this simply confirms that, with two consoles essentially at parity (level out the different spikes for price cuts, etc and adjust for launch and the 360 and PS3 worldwide are essentially neck and neck) few third parties are willing to be exclusive, and that only first party titles or negotiated (in whichever fashion) exclusives by third parties will exist.
Apart from the odd big exclusive (GT5, Halo) or notably skewed franchise by fanbase (FFXIII) most third party titles sell more or less the same (adjusted by install base) on each platform - so this should hardly be a surprise.
Try to be reasonable... its easier than you think...
