Ever since the Endurance Run I've wanted to get into the game for myself and didn't have a PS2 anymore. With the introduction of the PS2 Classics I was waiting for the inevitable release of the game, especially after the release of P3 FES. And now with P4 Golden on Vita it seems like there is no reason for them to put it out on PSN. Why put the game for $10 on PSN when they have a full priced game that could potentially move a few Vitas.
Aside from Endurance Run nostalgia, there is ZERO reason I'd ever go back and play vanilla P4.
Golden is just... so much better. Holy cow.
If anything, hope for a PS3/N/4 port of Golden. Seriously - it's such a good version of the game that I have no qualms about there never being a re-release of the original P4.
