I'd do the same. Much as I'd like an X9, I do not consider the SNES the pinnacle of X-series design. X4 and Xtreme2 stand every bit as well as the classics, whereas X3 I consider a decidedly below-average game. Unlike an NES-style Classic game, which handled decidedly differently than any other MegaMan, there is nothing unique about the SNES-style X-series games besides buster SFX and the fact that double-charges use both arms. The sprite style is flawed, it doesn't allow adequate detail to player-sized character bodies. The SNES is capable of better, and I'm not keen on returning to a style that can't even display Zero's armor properly. The level of "charm" afforded by the game style is no greater than a current ZX game, and the same can be said of the general feel and physics.
If X9 does go 2D, which I would by no means object to, there's no reason it can't do so in its own style.
