Sequel inbound?

To avoid a crapfest of an E3 show, tons of companies are doing pre-event events to show off their wares to the gaming press. Activision's got one, EA has one coming up, and apparently Nintendo has a card up its sleeve on this front too.

According to the latest IGN Nintendo Voice Chat podcast, editor Craig Harris is supposed to be shown a "mystery game" of Ninty's later this week, and it's so secret that they won't even tell him what it is.

Nintendo a while ago told retailers to reserve a bunch of shelf space for this holiday season, so obviously they've got a big gun or two in the pipes. Could it be the fabled Kid Icarus revival? F-Zero Wii? ExciteFox? Pikmin 3?

What do you think it is?
