That's a pretty good list of developers. Aside from Square Enix they're not really missing anybody there. Compare this to Nintendo who realistically will probably initially not have Rev support from Konami, Rockstar or Tecmo. But of course this all depends on what they actually get. The Xbox for example had Capcom support but it wasn't that great.
Still looking at this list it becomes clear that Nintendo has to step things up for the Rev. They currently don't have this amount of third party support or first/second parties and they kinda need to for the Rev to take off. Nintendo should look at this list as a checklist for supporters. Their goal should be to have 90% of the publishers on this list on board for the Rev.
