I was thinking..there's only really 2 guys in the Mario universe(excluding evil ones), yet there's 3 girls, so I think it'd be funny to have Peach hanging onto Mario, Daisy hanging onto Luigi, and then Rosetta from Mario Galaxy getting angry because there's only Toadstool left(or Rosetta hanging on Mario, since she is I'm sure considered prettier by some), possibly with the other characters(1 or more) specifically pointing to Toadstool with a sweatdrop or something.(indicating that Toadstool is the only choice left)

I liked the Roctopus, but could we get Gir wearing headphones?

I recall in a Warcraft 3 video (inside the game) that there was an armored man (paladin?) I believe it was the end of the human campaign. I would love a cloak like that.

I would like to see a console wars style t-shirt, with PC's whispering into the rulers of each home console.

Perhaps even go so far as to include the iOS hardware in there, with portable consoles even getting mixed in.
