It shows a want for the game first. Second, a lot of people don't have a Wii. I would hope they remake it for the 360 because of the fact that most Americans(which preferred Chrono Trigger more anyways) own one, or second the PS3 because of the awesome graphics.
There's dreams and then there's just plain delusions. Remakes for current gen consoles just aren't cost effective...and 360? C'mon...not gonna come close to happening. It shows interest for the SERIES, but not a remake. If you've already just played the original version, the likelihood of you going out to buy a remake isn't going to be that high, even if it is for an awesome game like CT.
It seems like it'd be more money for Ninny than it'd be for SE...SE could make more by handing the remake project over to a secondary company like Matrix Software to make a remake, release that and then, if they want they can release the ol' 16-Bit 2D "classic" version on VC after they see the awesome amount of sales they'd get from the venture.
From the business perspective, VC just helps to support Ninny a lot more than SE...
