When will the next G5N units be introduced on to the market? Is this the 2nd year for the Helix Mega SI G4N? I cannot find any stock in Canada for 9, 10 or 12 in the Helix. I am assuming that these units are on a 2 year cycle before new units are introduced. If I cannot track down a unit until later this year I was thinking that it may be an idea to wait until the new units are on the shelves next year. Thank you for your help
