The fact that it's an "original title" also indicates that this is a new IP, marking the first time the studio has designed its own game from scratch. Judging from the quality of Ready At Dawn's PSP titles (Daxter, God of War: Chains of Olympus), we're expecting technically great things from this new project. As for whether the game's premise is any good, we have nothing to base our expectations on. One thing's for sure, though; we can't wait to sink our teeth into more details.
[Update: We reached out to Didier Malenfant, co-founder of Ready At Dawn, who told us: "We are working on two projects at this time, codenamed R6 and R8, but haven't officially announced platforms, genres or publishers for that matter. The third version of our engine is up and running on all current-gen platforms and looks awesome while version 2.0 is still arguably the best tech around on PSP so we've got all our bases covered. Oh and by the way, we're hiring :) ]
