OP point is rather obvious and no one has ever said the PS3 can't handle Splinter Cell... what this prove is another no brainer that some people actually objects to!
I've stated many time before that people who think all these third party (big) exclusives (ToV, Star Ocean etc) are without incentive from MS/Sony are either delusional or talking shit. Money is the root of it all and MS with more money and less internal studio to sink that money into is doing what it needs to keep the fans the happy and 360 competitive. What else are they gonna do?
There is a certain amount of negativity attached to the concept of 'bought' exclusivity which was absent during the PS1-2 era when Sony was doing it left right and center. A large part of this is fanboy bitching but I believe there is also a certain amount of hurt feeling from the Sony fans who were too young to have felt the stings of betrayal when publisher abandoned Nintendo/Sega (Square buddy here's to you!) for the richer pasture of Sony. Another factor was that many of these exclusives don't stay as such, a year later they hop on to the PS3/PC ala Gears, Tales etc, often time with more features which makes a minority of multiplatform owner annoyed and a plethora of fanboys even more annoyed.
In any case, I like a forthright fella, and our man is probably under contractual obligation to not discuss monetary issues... it is at least more straightforward than the garbage they spew out earlier about brand affiliation blah blah blah....
