Indeed. when it's a tech demo, it'll most likely stay a tech demo. It it were not, I'd have seen a remake of ff8 (and believe, I so want one) or ff7.
Yeah, tech demos are just that, demonstration of the technology. N64 had a tech demo that featured FFVI characters Locke, Terra and Shadow battling a Golem in 3D. Of course, it was JUST a tech demo. That's why I laughed so much when Square Enix did the whole FFVII PS63 tech demo, and people suddenly jumped to the conclusion that it was a remake. EVEN though, right before that, they even stated it was a tech demo. It was a real hilarious thing to see, because perhaps people's hopes blind them in the same way people make total fools out of themselves when they are in love. The whole bit went like this, basically:
SQUARE ENIX: This is a tech demo showing the opening scene of FFVII, rendered with PS3 models.
PEOPLE: Oooo, looks pretty. Cool, a FFVII remake!
SQUARE ENIX: That was a tech demo, we have no plans on remaking it.
PEOPLE: But.... that was a remake....
SQUARE ENIX: Tech demo!
PEOPLE: Remake?
SQUARE ENIX: T-E-C-H D-E-M-O!!
PEOPLE: So....... when are we getting this remake?!!
