I prefer my Major Jones to look like a military woman rather than a fanboy-service sex object...so I go for the version in the game, and I also loved Eve's voice acting.
Anyhow, looking at this link:

Looks like this *isn't* going to be a sequel...but a re-imagining. But I'll still go for it to support the project. I'd be happy to replay a reimagined version of the original if it means I'll eventually get that sequal.
