1. if you are a big fans of pokemon... why aren't you owning a 3ds/2ds now? there is pokemon x and y..

2. 3d can be turn off if you don't want to use it... if you can't afford to own a brand new one wait awhile after the release of omega/alpha... people with thinking like you will start selling their 3ds/2ds and you can get it cheap...

3. the latest firmware is the best.

4. if i were you i would make my own decision
