I think the only Zelda game that will be announced at E3 will be PH, no new Zelda just yet. As for your other predictions Mario Kart will definetely be mentioned, hopefully some footage will be shown, there has been a lot of speculation about this title from NOE.
As far as your other predictions go the one I personally hope for is Kid Icarus Wii, seeing how Pit is playable in SSBB, it has a good chance of seeing a revival. If they do it, I hope they'll use the same engine they used in Zelda:TP, I think that would work really well for Kid Icarus. I believe it has been around 17 years since Kid Icarus for the GB was released, it seems time to release a sequel :p.
