I'm still most likely going to pick up a 3DS at launch, but my decision would be made a lot easier with a list of launch games.
The problem is that with the online capabilities mostly gimped at launch, the system's launch depends completely on its games. Yes, there is the AR which I look forward to, and fun to be had with the 3D cameras, but those can only entertain for so long. If cheap, downloadable games were available at launch, it would make the system a lot more appealing. As it is now, I would likely have to spend about $353 (with two $40 games and NJ sales tax) for the system to keep me entertained long enough to make buying one at launch a good option.
So then that leaves the question of whether or not there will be two games worth buying at launch. It seems very unusual to me that six weeks from launch we still don't have the line-up of games.
