Quote from DI @ the gear page
At this time, no dealer is aware of any shipping date. I get asked this question at least once a day (from sales, marketing, customer service, etc.), and maybe they're passing along their best guesses to dealers, distributors, artists, whomever... but the Helix team's answer hasn't changed. So unless you hear it from me (or Ben or Dale), every date you read is pure conjecture.
If something happens and the date slips, I'll let everyone know, but right now, we're on schedule.
