I'm not picking up the 3DS at launch. I actually don't see myself getting it for a year or maybe even longer.

The launch line up is mediocre at best and the games following at mostly remakes of older games. I probably won't be that interested until more information comes out about the new Mario game. That will be at E3 and the game itself, at best, won't be released until the holiday window. Unless they have a good holiday bundles (Mario Kart, Star Fox, OoT), I won't be getting one this year. I agree with the IGN guy who basically said: "the 3DS is not going to have trouble selling this year, so there probably won't be any bundles."

I am looking forward to playing the next Paper Mario game as well as the GB and GBC Virtual Console. But, that game and those services aren't part of the launch and will be there when I eventually pick the system up.

As of today, I have 93 games that I own that I haven't beaten. I'm not in hurry to buy a new system.

I picked up mine this morning with a copy of Super Monkey Ball but spent most of the time going through each of the features. It doesn't take very long to do everything in AR Games and Face Raiders, and everything else is mostly standard such as creating a Mii and changing all sorts of settings. For Super Monkey Ball I can only ask wtf they did to this series. Since when did the racing become a generic kart racer?  Same goes for the side scrolling fighting mode. The mechanics and physics behind being in the monkey ball during racing and such is what made it interesting and unique but now that's limited to just the puzzle/main mode.
The updated friend code system is nice, so actually having a single friends list that's updated in real time when you're connected online, only took Nintendo long enough. The other features like the web browser of course have to come later so what the system can do currently is very limited. The only other thing I feel to mention is that the cameras...suck. Very low quality and when rendered under the clean 3D models in AR Games it somewhat clashes, oh well.
Street Fighter is the best rated game so far, but I'm not into that series too much so if nothing else strikes your fancy I'd wait a while until this summer at least.
