Microsoft and Bizarre Creation's hotly-anticipated new Project Gotham 4 will also incorporate a new version of the developer's hit, dubbed Geometry Wars: Waves.

Apparently, Waves won't also be released on the Live Arcade and will instead be a PGR4 'exclusive'. Geometry Wars: Evolved was bundled in with PGR3 in a similar fashion, but was also released via the Arcade allowing non-Project Gotham purchasers to enjoy it.

The game was mentioned in interviews with website Pro-G taking place at the Leipzig Games convention this week, and while details are scant it seems this title is a spin-off from Retro Evolved, rather than an entirely new addition to the series.

More soon.
