I think I'm looking forward to them both equally.
I have yerned for this Zelda ever since I beat WW. A return to the old style (not graphics style), with horse-back riding and of course, adult link. This Zelda is looking like it might be the best game in history, or at least the very best of the series (which is basically the same thing, depending on who you talk to). But that's not all, with the Wii, it could become THE game to play. Some people have dismissed it already due to the E3 impressions (though I didn't hear anyone complain about fishing), but that's foolish. There is so much potential for a game like TP on a console like Wii. Together, they will bring about an experience that players have since only dreamed about.
On the flip-side, SSB has been an incredible series aswell. I've logged in countless hours on both, and I could still pick it up and play it if somebody is down for a little rumble. Now, with the addition of even more charachters, stages, items, modes, maybe some Wii-functionality and lets not forget....online, I don't see how anyone could not anticipate this game as badly as a drunk fat dude anticipates late night taco-bell.
They are both going to be amazinig. Who cares which one comes out first? Just be glad they are both coming out for Nintendo, and that you're a Nintendo fan.
(still, I hate how other great games are getting lost in the shuffle: mainly MP3 which is sure to be the best Prime of them all -- and maybe the best metriod yet? (although Super Metriod nailed it in every way))
