I know the feeling. There's an anime convention in this one place in a couple of months, I'm saving up for, and also I'm paying off some other "stuff", so I'm going to have to maintain what I need to save. I'm confident I'll have enough for a Vita and Persona 4 Golden before release date...I hope.
Persona 4 Arena is a day one go to the store and play the living day lights out of it, for me. i already have it pre-ordered with the additional colors and soundtrack. I'm possibly planning to getting RE6 on release date, but I might pre-order it depending on my mood.
I'm thinking of buying the remakes due to the fact it's the same games but with more gameplay, better graphics, and more content added.
I'm really interested in 3 and 4 myself, and I already pre-ordered the 2D fighter already with the additional colors and original soundtrack. I hope they include art books or collectables later on. I'm getting a Vita for Persona 4 Golden since that Persona 4 Arena, and begrudgingly for now Resident Evil 6, are on my hype list this year.
