yeah, i could see a second version adding 3 or 4g. But I don't really know how neccesary that really even is, I mean there are wireless access ports everywhere where I live (Minneapolis), playing my dsi games online has never really been an issue.
Aesthetically though, I do not see the complaints at all, I think it looks really kickass and stylized. A few squared corners alone, wont be enough on its own to merit a second version, so another model would have to offer more, like 3 or 4g, and I dunno, theres nothing more I'm really looking for in this system, it has everything I could want. It would be cool if it had skype for video chatting, but I don't see why thats not a possibility with the current version. In fact since Pokemon black/white can do it on the DSi, it would be really stupid not to have a skype app for the 3ds.
