On one hand, because the Wii U gets so few games, every new game gets scrutinized with "Is this the game the Wii U needs right now!?". Looking at in the context, would Retro had been better served creating the kind of Western action game with an aesthetic and style that Nintendo's Japanese teams don't do? After this year's Rayman, Sonic, 2D and 3D Marios, did they need to add another mascot platformer to the ranks so soon? And one that looks like an upressed Wii game at that?
On the other hand, I must prefer DKC to the MP trilogy, and DKCR was one of my favorite games of the generation. A sequel, in HD, with normal controls and a brand new David Wise soundtrack sounds like a dream to me. I'm pretty hyped about it, personally.
Way I see it, its kinda like my relationship with Valve. Do I want them to make Half-Life 3? Goddamn right I do, I need some closure here, mothafucka. But if their passion lies towards L4D and Portal and DOTA2, and those games are very good in own right, well, I can't complain too much about that, even if something like DOTA2 doesn't appeal to me. They maintained a level of quality rarely seen from any developer to dabble in that many games this generation; no doubt in my mind that if(AND WHEN) HL3 comes out, it will not only be because they want to make it, but it will also be very good.
If this is what Retro wanted to do and its very good, I'll take it, gladly. Maybe not the best choice in the current context of the Wii U, though.
