I'm also fucking glad that we're getting a real in-house sequel to an old favorite, which is too rare.
Yoshi's Island DS (by Artoon) being a sad one, obviously DKCR wouldn't have been by Rare so that's fine, plus Retro's awesome.
Luigi's Mansion 2 is by Next Level, so I'm very skeptical.
To me Kirby's Return to Dreamland is essentially Kirby 64 2, or Kirby's Dreamland 5 (64 being 4), and that's by HAL, and it's awesome.
Pilotwings Resort isn't really a Pilotwings, it's Wii Sports Resort with the name pasted on it, but Monster did the grunt work, actually it's better this way than in-house as it shows Monster is still close to Nintendo.
See where I'm going? I'm positive the original team will be behind Pikmin 3, no way they're going to pop up and say "Guess what, our 3rd-party partner _____ is behind this!" Wouldn't make sense who on Earth would they even pick? Just don't.
