I have been screaming for a Mario 64 2 ever since the original came out, pretty much non-stop. After all those years to me there still hasn't been a platformer that comes anywhere near as close to perfection as Mario 64 has (on anything).
So... Yes!
I'd also be more than fine with Sunshine-style open-worldness. Was pretty much the only thing the game did right. Galaxy 3 would be awesome, if it includes at least a big hub-world bigger than the observatory, entering 64 territory (and if it was called 'Universe'). That level select screen of Galaxy 2 was a huge step backwards.
