Since I have no access to inside info, I cannot correctly say one way or another. However, everyone should bear in mind that even if new shares have been introduced into the market (thereby increasing the float), hubba's sharecount does NOT include the entire shareholder base, many of whom do not even know of IHub, much less read it.
While in SEK, I met up with another HMGP shareholder who's 'crowd' of investors were of an echelon where they invest by DD and not by chatroom commentary, never even frequenting chatrooms for their choices.
Though I cannot in any way, accurately guess what the total o/s is (real, and air), I think I can safely say there is a good 10M airshares, with the possibility of a total of 20M or more.
