NOPE! I picked Pokemon White in 2011 and I stayed on the White side by picking White 2. WHITE POWER!!!Should owners of Pokemon White buy White 2 and vice versa? I suspect that it would benefit you to buy the opposite version given how you can experience things you missed as well as obtain version exclusive Pokemon you may not otherwise have.
Bought White originally, so this time I went for...Black 2.
Funny how it seems that nobody is going with a Black 1/White 2 pattern though.
