I agree with what Miyamoto has been doing with the Zeldas. I've played and beat almost every single one of them.
Remember what happened when he tried to take Zelda too far of course? Zelda 2 for nes...
While it was not bad on it's own, (and a precursor to later castlevania games and sorta like metroid), it wasn't really as good as other Zeldas and strayed too far.
And Twilight princess is really the best one so far. The motion controls make you feel like you're part of it but they don't go overboard with it. As far as wii-motion plus for the next, I REALLY hope so. Or if possible he could "enhance" if you have it, but still let you play without it. I'd prefer though to see some really interesting sword mechanics in it. I basically bought the wii for stuff like red steel thinking the sword control was already 1 to 1. So, any sword game with motion+ is really appealing to me.
And the phantom hourglass for DS is pretty tight. It's got the best boomerang aiming ever in a game. Plus, the ability to take notes in game on the map is TIGHT! All adventure games either need this or a really good system to track goals for you (like Fallout 3). But being able to circle something on the map and write "need bombs, go here later" or something is tremendously useful when you play it in small chunks of time throughout the week.
