There's the IGN preview... here is a summary for those who are too lazy to read it:
- A pretty tough difficulty
- Can play as both X and Zero "forms"
- The game is taking a page from Castlevania / Metroid... this has got me really excited:
Since the world is essentially divided between human and machine, players will not only have to use the Mega Men models, but also navigate neutral towns in human form. There's far more general exploration in the game (almost like Metroid: Fusion for GBA or Castlevania II: Simon's Quest for NES)
- Homages to the old series
The game is going to be awesome. Capcom is on a roll with awesome games lately.
