Dude, are you serious!? The DS has existed since 2004. The 3DS will be released in 2011. This means that the DS existed for 7 years! I was starting to get annoyed with the Nintendo DS's life span! Nintendo shouldn't prolong a device's life span by releasing sub versions (DS Lite, DSI, XL). The DS wasn't even that good compared to the PSP, graphics and processing power wise. However, the 3DS will trump the PSP with its hardware. This will allow game developers to try out newer and funner ways to for game play. I'm actually really excited for the 3DS. I will say that it is expensive, but it is expensive for a reason. I may have talk to some people and get a temporarily job to save up for the 3DS. School is tough on me financial wise, which means I'll have to work a little extra hard to afford the 3DS. Why don't you get a job and save up for it? $300 dollars is like 2-3 weeks of working. After that, you will have it for years and years (assuming you treat it good). Also the games aren't that expensive, so it won't cost too much to get a decent collection. I don't see whats the big problem?.
OoT for the original DS? I don't think the DS's hardware can handle it. The DS was a nice piece of hardware, but it's hardware didn't trump the N64. It was able to handle a few N64 games, but it most certainly can't handle them all. The 3DS however, does trump the N64, and can probably handle most, if not all, N64 games. Like I previously said, I'm excited to see what game developers are going to do with the amped up hardware.
