Should it be re-made in 3-D? I'm going to quote Will Smith by saying "Oh HELL no!" The game was fine in 2-D. In fact, it was pretty much at the peak of SNES graphics. The only reason Square shifted from 2-D to 3-D is because they could.
Well, that plus the fact that Sony doesn't like publishing games for its consoles that they don't feel are really using the hardware effectively.
