The only thing ill care about is what multiplat RPGs are 1080p on what platform. If there is a really good RPG that comes on all platforms but is only going to be 1080p on the WiiU, then I would probably buy it on the WiiU. Not that it would ever be like that, but that is how it works for me.
If a exclusive RPG happens to be 720p on my PS4 I will not care nearly as much, though I may wonder why its not 1080p.
