Shouldn't it be the other way around? 3DS is cheaper and has the bigger/better library now, so get that now and wait until Vita drops in price and its library has grown.

yup

Should probably get a vita because of region-free. Then get a 3DS used or something that is for your country. Either way you save money.

Also fast food.

As a guy who prefers Sony to the others, i bought the 3Ds and im quite satisfied, but then again i have only bought 3 games since I bought it in April. and two of those are Marios. Honestly if all you care about is Mario and Pokemon, I would hold off on getting a 3ds for now, especially since it is region locked. I have Vita as well and its a good system, bough four games since buying it back in May. That might be more up your ally with the store and cross buy and what not and its not region locked, but i would still say wait on that one too.

Careful, 3DS is NOT region free. You'd have to import all your games, you up for that?

It's hard for me to recommend Vita right now, though there are quite a few great PSP and PSone games available on the service.

But the 3DS isn't region free, so I'm not sure buying an American system will work out for you. It has a bigger, better line up at the moment.

Depending on what kind of games you like, a 3DS could be a good match if you don't mind importing.

I'm anti Nintendo, but Nintendo handhelds are always worth owning. Since you don't have a DS already, then the 3DS is a great console to own because while the 3DS doesn't have many good games, the DS has a ton of great games.

I own 11 3DS games so far and one game is currently pre-ordered.  Personally I think that's a lot.  The thing here is what would you consider a "good game" as many people have different ideas on what they are.  Getting a 3DS is a great option nonetheless because you can play any 3DS and DS game on it, and the DS games aren't region-locked.  A PSVita also has access to many good games, but it requires you to buy a larger memory card.  It really depends on what you're looking for (most of this directed towards pezus).

Vita needs the support more.
