To be honest I'd be reasonably happy with Wii U level of Western third party support, just a bit more effort on the sports games (FIFA/Madden NFL/NBA 2K and hopefully NHL). I don't expect Western devs to go crazy on the platform because it's unlikely to be the market leader in the West, but it would be nice to get your Western shooter/action game fix and sports games are important.
For Japanese developers, I want better support. Not just Monster Hunter and Dragon Quest ... I want Final Fantasy, Kingdom Hearts, Soul Calibur, Ridge Racer, Metal Gear Solid, Marvel Vs. Capcom, etc. the whole pie, not just two pieces of it.
The 3DS is the rightful market leader in Japan and Switch is its successor, and if its possible to run said franchises (and I believe it is), then Switch should get all of those IP. Not just 50% of them.
