Just talked to them, it is pre-order only as of now. Expecting to be shipped out with the 2014 line of products, so Sept (late fall/early winter) according the guy I talked to.
Bakes ActiveWake and WakeMakers all have the Eight.3 Plug and Play bags in stock. The Eight.3 Telescope bags and pumps are on their way. A realistic ETA would be the first or second week of September. I used the new system this weekend and was impressed with what Ronix was able to create. It fills and drains fast. You guys will be stoked.
