Maybe it's just a question of not growing too rapidly.
As far as I understand Guimbal is very busy and the lead time for a factory new G2 is quite a while. If Bruno opened up a new market in the US right now he might displease potential customers in Europe or elsewhere.
Grant him some time to increase the production line in France and I'm pretty sure that soon or later we'll see one or the other G2 in the US.
