on the one hand, XCom was dragged through the mud many many times, so Firaxis's take on it can't be that bad. on the other, look what Fallout 3 did with the Fallout name. the new generation of players won't care about the original, they'll be all, "wow, what a nice game, Firaxis is the best studio ever, they had the guts to make a true tactical game in the age of shooters. oh wait, it's a remake? ah, who cares, I probably won't be able to run the old game on my system".
