I want Lumines Vita (been waiting for a good sale on that) and Persona Arena but only have enough for one of them. Think i'm going to go for Lumines. If it was going to go PS Plus it already would have and I can see PArena going PS Plus with the new one coming out and the DLC available for them to make money off.
I really don't want to double dip for FFXHD on release day. I know the Vita version is the one i'm going to be playing the most, if not completely on, but I don't want to be kicking myself for missing out on the PS3 Limited edition version. Tough decision.
Go for Lumines. P4A is always on sale since it's Atlus. This is the first time Lumines has ever gone on sale. Maybe the last.
Go Vita. Limited Editions are whatever. Don't let them take so much of your money.
