My thoughts on your wishlist (for the Wii U)
cod mw trilogy (1,2,3) - Why? all CODs are the same with different maps, this franchise burned out long ago, i could go a lifetime and never play another one and be totally fine with that.
conduit 3 - Meh. The Conduit games were OK, nothing to really write home about, but I did like that they were at least a little different than your standard FPS. I couldn't care less if it ever had another game in the franchise or not, but if it did, I'm sure I'd try it at some point.
dementium 3 - No opinion. Never played the first 2.
dragon ball z budokai tenkaichi 4 - These games are fun, I'm not personally dying for another, but I'd play it if it came out. Seems most likely to happen so far from your list.
excite trucks u - Excite Trucks? Really? Did you ever play ExciteBots? That was a substantially better game, I'd be more excited for a sequel to that over Trucks. Even Still when MK8 comes out, i'm not gonna give a shit about any other racers for a long long time.
gta 4 or 5 - Yes, port over 5, I agree completely. They could make switching weapons and characters and all sorts of other stuff even more easy and intuitive with the Gamepad. I'm with you here, but I don't think its gonna happen. Rockstar and Nintendo do have a relationship though, so I wouldn't discount any GTA game from ever appearing on the Wii U.
house of the dead u - Yeah, I could be down for some more House of Dead, its been awhile.
madworld u - I initially liked Madworld, but the gameplay got old fast. I did love the constant very humorous commentary from Greg Proops and Jon Dimaggio though, so I think with some refining to the gameplay by adding more fresh ideas and more different types of levels, i could definitely get behind another one, but it couldn't simply be more of the same.
megaman legends 3 - Good luck, not gonna happen, and even if it did, it would be on the 3DS as planned, not the Wii U.
mass effect trilogy - I'm not one to care about repackaging games that have long since been released, but at least this would be more interesting than a COD trilogy release.
metroid other m 2 (or prime 4) - Most people hated Other M, so I doubt a sequel would ever happen. Everyone loved the Prime trilogy, so Prime 4 could happen. I don't think Retro is interested in doing anymore Metroid for a while though.
sonic generations - Again with games that were already released, why not just make something new instead. Make Colors 2, that would be my advice.
tatsunake vs capcom u - I liked the first one, I could play another. If not Tatsunake, then some other Capcom vs. game, they are all fun
sonic adventure 3 - ugh, I may be in the minority here, but I hated Adventure and Adventure 2. Sure some of the Sonic/Shadow stages were fun, but the rest was a total letdown. Sonic Colors and Generations are how 3D sonic games should be made from here on out, heck even Lost World was a bit of a misstep, but I'd def take another one of those over another Adventure, '06, Unleashed, Secret Rings, or Black Knight.
