Ok the important issue should be addressed first.. YES I'm gonna buy The Conduit :P
I think you're right in a way, Nintendo started out downstream and are going to continue to build on those downstream games (this means games for people who are new to gaming), but their ultimate goal is to get these new gamers to play the traditional Nintendo franchises i.e. they want to upstream these guys.
You can see evidence for up streaming in Mario Kart Wii, a traditional Nintendo title that is bridging the gap between downstream games and upstream games. This will continue and I expect ExciteBots, Punch-Out!! and Pikmin 3 will be the next main 'bridge titles'.
At the same time however, Nintendo have released Mario, Paper Mario, Zelda, Metroid, Super Smash Bros., Battalion Wars, Fire Emblem and Excite Truck and all of these games came within the first 1.5 years of the Wii's lifetime. Galaxy was supposed to be a launch title, Imagine that, Wii Sports, Twilight Princess AND Mario Galaxy all right there and after Galaxy got delayed Metroid was poised to fill it's position! Imagine if that did eventuate, there would have been a lot more gamers sooking about Wii's software library then as less spacing would mean more drought..
Nintendo have had spacing issues but they are supporting all kinds of gamers whether it be downstream (Wii Fit), Bridging titles (Mario Kart Wii) or hardcore titles (WarioLand) all released around the same time.. The issue for Nintendo is to get the downstream gamers to enjoy and want more upstream games like Zelda and Metroid because the sales figures clearly show that the upstream gamers have no problem playing Mario Kart and buying Wii Fit.
If the rumours are true then we'll see downstream games including Wii Sports Resort and Wii Fit Plus this year, we'll also see more bridge titles in ExciteBots: Trick Racing, Punch-Out!! and Pikmin 3 and we'll see a bunch of upstream games such as Kirby (hopefully), Sin & Punishment 2 and perhaps games from Monolith Soft and Retro Studios which both will be due for a game between Q4 2009 and Q4 2010.
Nintendo have the net cast out very wide and I think they're doing an excellent job at achieving their goals so far. There's going to be a new Zelda, a new Mario, brand new IP's from Retro and Monolith Soft, and also a bunch of great third party content like Grand Slam Tennis (a bridge title), Red Steel 2 (upstream), and also downstream games such as EA Sports Active and Boom Blox Bash Party. It's an exciting time in the world of gaming and for Wii it's only going to get better.
