Nintendo is the only console maker with a desirable catalog of IPs. Sony and Microsoft have less franchises, they don't push them hard either (because honestly, Nintendo doesn't push most of theirs either), and they're similar to what's being done by third parties.
Yes, there's a crap ton of 2D platformers out there (specially indie), but there's a lack of F-Zero, Metroid, Punch Out, Smash, Mario Sports, and casual titles such as Brain Training, Dogs, etc.
The new God of War looks very different from what it used to be, Wipeout is dead, Twisted Metal is dead, etc.
Gears and Halo are more shooters, and that's about anything relevant Microsoft has.
In conclusion: If Sony and Microsoft were going bankrupt, not as many people would want them to go third party due to their lack of IPs, and the existent ones being a little too similar to third-party games.
