They're starting from a very low base, so in my mind this isn't an overpromise. They've really only had a handful of sales total, so doubling isn't exactly that difficult.
I would be concerned if they didn't more than double, given how much they've shown to be in their pipe - I'm thinking of the graphic with the different sized circles, a good number of small ones in the past (the left of the picture) and the enormous ones in the near future.
