So, is it too late to change my answer? Haha. Ended up getting a 3DS XL really cheap a little while back, and converted to playing White 2 on it instead. If I recall, I can't use Dream World because of the switch, but I don't think it's that big of a loss.I've just been playing White 2 on my DS Lite. There are very few games that I can think of at the moment that would make me want to upgrade to a 3DS, so I'm probably going to hold off until the main series games are exclusively on the 3DS- especially with my DS Lite in pretty good condition.
Playing BOTH Black & White 2 on DeSmuME and on a Nintendo DS Lite. I prefer DeSmuME because I'm going to start doing VIDEOS in a couple of weeks, so STAY TUNED.
