I've just been to price up the Vita on pre release. Holy cow!!! If you get the 3G one + a memory card (required to do anything according to the shop assistant) it works out at over 300 pounds (In England at the moment). My sister in-law has just brought a PS3 (it was the cheapest one) at just under 200 pounds.
So when i thought it would be the same price as a PS3 i was wrong. It's aproximatley 30% more!
I'll still get one though. However, I do think Sony rely on fan boys like me far too much!
