I'm less surprised, only because more of us early-adopters that are Mantic fans likely have a predilection for fantasy games over sci-fi. Warpath rules haven't completely won me over, although I think it's something worth showing off. (It's not that I think it's bad, but I just don't think it's as strong as KoW.) Even with that, the FF minis alone grabbed my attention and made me want some, and the background that has been discussed makes me interested in the game universe.
But even great sci-fi pulls me less than fantasy.
So, all-in-all, I'm not shocked by this. In a year, it will likely be a different story. At least, in the US, I'd expect us fantasy fans to be rapidly and soundly outnumbered by the sci-fi ones here.
I have to admit that I'm a bit surprised so many of us are in the same boat.
