I'd say the Miz's awesome title reign, but I see them pulling the trigger on that before 2011 so...
Sheamus/Taker
Taker/Cena @ WM
Joe reinvigorate the stagnant TNA title
That Florida outfit, just to see how they do
Kaval/Bryan get 30 minutes and allowed to go all out
Husky Harris get some play, perhaps become the next Umaga type heel
Barrett/Trips...dunno, just think these two would have an awesome match
Cody/Morrison...just think there is enough there to have a really good feud, like who's prettier
Give a HOFer the WWE President slot and let him reign very moderately over both shows, like in the good old days
Some one to feud with the Hart Dynasty, just more tag teams in general and not thrown together teams, real teams
Rey/Borune, Rey/Kaval, Rey/Bryan, Rey/Tyson Kidd,
Jericho/Christian one more time, Jericho/Sheamus, Jericho/Bryan again, Jericho/Kaval
