ds or 3ds

[cloud1161]

i posted a thread a few months ago about this same topic, but im bringing it up again since theres more information regarding certain consoles and what not.  let me start by saying im definitely getting vita within the first few months it is out.  second, i am an rpg fiend and thats the whole reason why i want to get a ds or 3ds is for the rpgs and jrpgs.  with these few ideals in mind, would it be better for me to get a ds and save a 100 bucks to play the 5-6 rpgs i want to play or should i just say screw my budget and get a 3ds?
