This is really great, and exactly what I think Nintendo needs to boost the 3DS to the kind of popularity all Nintendo's handhelds since the Game Boy have had. And I'm sure come Christmas time more than a few people will be swayed to the 3DS over the Vita due to the price. And normally I wouldn't feel as ecstatic about it because I had to spend more on it, but I do get something in return for spending that money, something quite nice. I have to wonder what the other games they'll be giving us will be, though, since I'm not necessarily interested in every single one of the games they're giving away. I am quite excited to get Metroid Fusion and The Legend of Zelda on my 3DS, though. It's a very good deal, even if it was just those games.
My only concern is to how this might adversely effect Nintendo as a company, because allegedly they're selling it at a loss once the price drops, so hopefully the price drop will be enough motivation for people that Nintendo will be able to stay very well on their feet.
