I can't think of a top 3, but I do have my number one pick:
1) Lylat Wars (Star Fox 64 for Americans). - Whilst it received a 3DS remake/port, I'd love to see a full HD version of the game, it has the potential of looking absolutely stunning.
Assassin's Creed trilogy. (Hell, I'd take an all in one condensed version with Desmond being able to jump into any of the eras at will and being able to partake in only the important missions and of course some free roam stuff)
