Personally, I thought that Nintendo gave me a very satisfying press conference by highlighting four - four - systems, along with software that tickles me pink. But I'm not a Nintendo fan, I'm more of an industry fan. I don't need to see Nintendo win - I just need to see Nintendo continue to offer alternatives to the "mainstream".
I mean, Sony has some great PS-only franchises - but they're running the PS3 campain on titles that end in 3's, 4's and 5's. Nintendo, on the other hand, steers clear of numbering their franchises (save Mario Party 7), because their franchises get overhauled and re-thought each generation - or, in the case of Zelda, each game.
Getting back to the point, yes, Nintendo did disappoint everyone who wanted to see Shiggy's new game, the Revolution's "Revolutionary features", and Nintendo pressure on Sony and Microsoft. But I, on the other hand, was delighted to see clear support and new directions for the GBA, DS, GC, and Rev. So what if they're keeping closed hand on tech specs and footage? They're a year away on the Revolution. It'd look worse than Perfect Dark 0 Screens.
You want a Revolution? Wait until Nintendo says it will have an impact on the market. I wouldn't be surprised if Twighlight Princess was released during the 360 timeframe - with a bonus disk of Revolution footage. That's market impact.
