I'll be honest: at first i was in the 'what are you doing to my XCOM series'camp, but now after reading the preview, i'm convinced
My only worry was about the change of genres: from tbs to fps. Thinking about it, that's the only way a new XCOM game could be made in this day and age. Video games have evolved and now they're a very imporant market. As long as they maintain intact some of the key elements of the XCOM series, i'm ok with it being a shooter.
Seriously, from the preview it sounds like XCOM, only the missions aren't TBS but FPS. Oh, and i don't really care about the changed setting. It's not like the original UFOs were very original in this regard.
