That's disappointing news! I'm looking at going later this year along with a friend who, like myself is a big Coke fan and he (unlike myself) hasn't been there since he was a small child and was so looking forward to it.
I will, however, say that I think the refurb is a good thing (even if the timing is questionable). The outside was a bit of a hindrance to Future World's theme, even if it was cool (pun intended) on its own, and the last time I was in there, I saw many of the same problems that some of you have (many of the fountains not working, sticky floor, no snow, etc.).
...That can be easily solved, though. If they make the outside more Innoventions-ish and do away with the snow (and any liabilities along with it), then perhaps when you enter it, the tunnel could now be a "Hyper-Freezing Chamber" or something, where mist is projected and it gets progressively colder and realistic-looking ice cickles hang from the ceilings and sides. Then, once you enter, it could be very similar to the old Coke room, but maybe with electric-looking lights running between globes on top of each Coke dispenser and the walls lined with a sleek metalic look. That way it's futuristic and "world community"-ish, while still offering (a)a cool theme, as opposed to a bland Coke station, (b)a way to get cold, (c)the whole notion of Coke from around the world. Just an idea, and with a 6 month refurb ahead, something this large-scale might be in the works! Or, like someone else said, it could go beside EE in AK, but that's unlikely.
