Spool Up

I saw on the Haltech site that the E11 is still not for sale outside of Australia as they are testing a beta version of it, but you can still buy the E11 from Australian vendors, and probably others. Does anybody know or have any clues as to what differences are going to be made in the unit before they release it internationally? I would really like to buy it ASAP for my TII but if there are still bugs in the E11 being sold now, I would rather wait until the unit is released officially by Haltech. If the issue w/ the beta version is only working out glitches in the software, then I would probably go ahead and buy it now considering that I can download the final version of the software when it is released. Does anybody have any information on what kind of changes they plan on making between the beta and final versions on the E11? Thanks
