I was hoping he would mention more about Metroid Other M, but these are some exciting "announcements". (Of course they won't officially announce anything because Nintendo are such teasers)
Motion sensing on a handheld has me worried though... Kirby Tilt n' Tumble was rather shit while Warioware Twisted was really fun, so it can go either way. Deep down in my heart I hope that they revive the old Gameboy name for this new handheld but it probably won't happen and might just be something like a "DS Advance" or "Super DS".
As for the new Zelda, I'm very hopeful for it. Twilight Princess was amazing but it drew way too much straight from Ocarina of Time and didn't give much in the way of a revolutionary title. From all the rumors floating around about this new Zelda, they are saying it will be a completely new Zelda game that will completely change up the formula. Here's hoping the new Wii Zelda will be to Twilight Princess what Wind Waker was to OoT.
