a record or two and some hax would be fabulous. would also be cool to see replays with mods, like environment mods (hi jisse) since the modding community needs a boost.

people who IMO should get in:
internet (duh)
NotNoob
Flash (would be good to get some tricking in like someone already mentioned above)
zeto
a double gravity replay would be really cool aswell, but make sure to say that it is double gravity in the title, a lot of people might not notice.
i wouldnt mind some more multiplayer aswell

and like jisse said,d it is somewhat pointless to have some of the old stuff in there for the sake of tradition. we could remove some of the stuff that doesnt live up anymore
