I sincerely hope not. DSi Ware is thus far a craphouse and I cannot imagine that selling an actually decent game on it would be easy.
I don't think a Wii game would be that bad, though, considering its development costs are usually lower than the other two, and it is plenty capable of handling the anime-ish style that X is known for. On the other hand, the last thing we need is X coming up with some excuse to use motion control (at least with Legends pointer-based aiming would make sense).
There is the mentality left over from GBC generation that portable X-series games tend to be side-stories. Which I'd be all for, BTW, but for an actual X9 I'm not sure if Cappy would be up for a DS release. X-series is generally a "retain classic gameplay but see what the new hardware can do" deal.
