That trilogy will be the thing that finally makes me use Steam. My body is ready.
I'm holding out for the PS3 versions.
It'll really piss me off if we don't get them.
I really wouldn't count on getting those. As has been discussed it's really more of a Sony thing than an Xseed/Falcom thing...
Well, we don't know all of what's holding up PSP releases, but it has been noted that at least on PSP they have eased up on approving games, and that the real hurdle for Monster Hunter 3 Portable HD not coming here may have been the servers. It is possible that by the time it's relevant Sony will have eased up if that's a problem, and it'll help that at a minimum they can bundle Trails in the Sky FC and SC together. Two games are clearly enough for collections as Ico, Tales of Symphonia, and God of War have shown. Even trophy-less games may be OK now, the Genesis/Mega Drive version of Castle of Illusion came without them though that was a pre-order bonus.
Still, I wouldn't get hopes up too high. There's too many unknown factors at work here, and it does seem likely that if they want to go for a trilogy collection it'll be too late to matter, though maybe with the Third being so much smaller text-wise they could get that out relatively quickly.
