I agree that 360 will remain largely unaffected. Generally the big-name projects that go there are fairly low risk, and the kind of studios that develop the bulk of 360's libraries will largely be unaffected. Studios that did PS3 ports (like whoever did Fallout 3 PS3 or Orange Box PS3) will likely be one of the first groups to go, but that won't spell doom for PS3 overall, it will simply limit those games that aren't being developed primarily as multiplatform titles (clearly in Fallout 3 and Orange Box's case, the intent was purely PC/360, with PS3 as an afterthought in either case). Multiplatform development won't falter, but those games that are strictly PS3 ports will probably suffer
Wii will largely benefit, as it is a lower-risk platform, but some of the games promising lower returns will get axed (stuff like Winter, but Winter's fate was totally unrelated to the current financial thing, just an example), DS will benefit for similar reasons. PSP will lose more western support (if that were possible), but remain steady in Japan.
Monster Hunter: pissing me off since 2010.
