If you read my posts in this thread, I called out main console entries:
This is certainly true. I don't need to bring up Graces f, and Vesperia on PS3 versus the other platform's performance in Japan. Heck, even the sacred Tales on Nintendo cow Symphonia sold more on PS2 in Japan:
[GCN] Tales of Symphonia (Namco) - 183,527 / 322,779
[PS2] Tales of Symphonia (Namco) - 269,073 / 394,312
Yes, Symphonia sold the most worldwide as a Gamecube exclusive. Symphonia was also marketed by Nintendo and was a big RPG on a platform without them in a time where that genre could still rule the west. That's being at the right place, at the right time. I don't believe Tales will ever again be capable of that success in the west after Namco's failure to build upon Symphonia's good will. It seems Namco Bandai believes as much too, since even with the weak sales of the western PS3 release of Graces f they're trucking on.
Never in any of my posts did I comment on the status and positioning of the escorts/remakes/ports until you brought them up.
Actually, SCEA of all divisions brought a Hatsune Miku Project Diva game to E3, and included it in their sizzle reels despite that series having absolutely 0 footprint in the west. It seems they're willing to work with partners who've supported them, and Namco Bandai with Tales would definitely be a partner.
As for Graces on Wii, wouldn't a better question be why Nintendo didn't step in to help Dawn of the New World? You know, it was the sequel to the best selling Tales entry in the west and all ...
