Predator killstreak reward - If the predator missile could be treated like the mortar team in Black Ops, I would be fine with it. The main problem lies in that the predator reward renders the map in realtime 3D. The Wii's RAM just can't handle bigger maps; thus, it was deactivated by Treyarch. I don't blame Treyarch for just deactivating it rather than trying to find a way to recode the streak to behave like the mortar reward. On the other hand, hackers/code users can incorporate the predator reward back into the game (since it was never actually removed but simply deactivated), but it can lag the game and it also is an unfair advantage to have a killstreak reward that others do not have access to.
New maps - never going to happen on the Wii. Just not enough money to be had for the time:effort ratio involved in porting them to the Wii.
Survival Mission mode - never going to happen on the Wii. Possibly could have happened, depending on the maps, but I have never played them or seen the maps to know if they are too big for the Wii to handle.
Missing single-player content - never going to happen on the Wii. You got the truncated version of the game, but isn't the abridged single-player version of MW3 better than no version of MW3 on the Wii?
The Wii U will likely have a much more secure OS, a free online network (yay, Nintendo!), and a real account linked to your console. These all add up to a much more secure system that is not hacker-friendly. Plus, it will have HD output, so ports will be much easier...for now. The only real trick will be coding for the new tablet controller. I am glad the system will still support the remote+nunchuk combination (for me) and the new x360-clone controller (for others). I really hope that future CoDs drop support for the n+c combination; that's the only way I have ever been able to play FPS and enjoy them (ie, not go 3-30).
