rofl do you people not keep your Nintendo news up to date *sighs*
Nintendo Revolution will be released during the week of thanksgiving (as was with Gamecube when it was released).
Nintendo has already confirmed in will NOT be coming out by March (the end of Q4). Nintendo is all about driving sales, (i.e Gameboy Micro another resdesign of the GBA) so don't question that they wouldn't "put it out be Revo" just because of that. People don't buy systems because they got good graphics, people buy games for their quality (like LoZ).
Numerous people bought Gamecube just for Legend Of Zelda games, but of course that was your opinion which in the future will turn to be wrong, because you haven't been following Nintendo like have for all these years.
And also, Nintendo backed up LoZ because they wanted to perfect the game to a greater detail. Which is something no other Game Publisher would do (which is quite true). So believe me Nintendo would not put out LoZ during the summer when sales are basically at their lowest.
Most people buy games in the Winter (around thanksgiving) because it is cold, and you can't go outside to play for very long. So your quote of "Never say Never" is partially correct, because Nintendo has never done the normal thing since n64.
So expect LoZ TP to come out either September or October in 2006, along with the Nintendo Revolution coming out around November 23-26th, 2006.
