I played Vesperia PS3, you're really not missing that much.
I wonder how many of the people whining about it would actually buy it if it came out today...
I agree, the improvements on the PS3 are minimal. Buut a few things to remember:
(1a) Not everyone has an XBox
(1b) Some have dead Xbox's now that won't play Vesperia360 anymore
(2) We've been pretty teased and strung along like a crush that won't stop flirting with you but doesn't want anything to do with you (like FilthieRich using the VespPS3 logo to his Graces teaser image; apparently additional voicework was on the 360 game and Troy Baker saying it was good to go; and that recent Playstation poll putting VesPS3 in its "RPG" category as an example for "what genres we want to see")
(3) It really hurts because it was almost *disturbingly* obvious that
something was missing in Vesp360 (see bright red arrows)
(4) The Vita "efforts" for the DS "remakes" have been really bad. At their best, they provide good nostalgia in a slightly updated form; and their worst, they look, play, and feel like they've been outsourced titles (which they are). I think Innocence-R may actually hurt the brand on Western shores, while Hearts-R made a few questionable decisions about what was changed up.
Word around the campfire is thinking the "secret announcement" is about Xillia 2; which might make sense as far as getting voice actors back to reprise their roles (just get it all done while doing voices for Xill1), but may be too soon.
