It looks a lot like Valkyria Chronicles, to be honest (gameplay wise; space marines vs. aliens is about as far from anime WWII as you can get).
Characters have different classes (sniper, assault, heavy weapons), and have different strengths and weaknesses. I was cautiously optimistic before, but now I’m convinced.
Firaxis’ X-COM remake looks like it’s the real deal.
Update: Rock, Paper, Shotgun has a three–part interview with one of the developers; he addresses a lot of the concerns with updating an 18 year old game for today’s market. It’s an interesting look into how Firaxis is updating the series and how they’re changing some of the mechanics.
