Not a hint to anything, but curious to read the room.
How would people here feel about a Super Mario 64 remake for Switch?
I'd prefer a new title. It depends what else happens around it. By 'new title', I mean if I had the choice, I'd take a new 3D Mario over a remake of Super Mario 64. If Super Mario 64 was handled externally, with some oversight from EPD Tokyo, leaving EPD Tokyo to make another, new game (not necessarily Mario), I'd be more interested.
I'm less interested in individual remakes than I am a balanced line-up. With a 3D World port seemingly inevitable, I'd rather see a new 3D Mario or a new game from EPD Tokyo next.
but it arguably replaced a new game of a similar scope
There's no real proof of that. Grezzo handled Link's Awakening with some help from EPD 3, and Grezzo are a small team. Their brief with Nintendo has almost entirely been remasters, ports and remakes, with the exception of Ever Oasis (which bombed, sadly) and co-development duties on Triforce Heroes.
Don't get me wrong - I'd take a new top-down Zelda over further remakes - but it's not as simple as 'X team made Y remake, when X team could make a new project'. A new project would be different in scope - it'd need planning, writing, level and map design and so on, which already all existed for Link's Awakening.
