t8 and nelson, please be patient. Pre-orders take a lot of time, and estimates for ship dates are always overly optimistic. This is true not just for Kebo, but for any manufacturer. I pre-ordered a Super-T ELA and didn't receive it for 4 1/2 months. But the end result was well worth the wait.
But beyond that, we've not even yet exceeded the estimated 4-6 week ship date yet. Your complaining this early only portrays you as obsessive, demanding retail customers who everyone who has ever worked in retail or customer service can't stand. This isn't retail. Be patient.
For any pre-order, it's a good idea to take the estimated wait time, then double it. If you receive your order earlier, you'll be pleasantly surprised. Otherwise, by then there most certainly will have been some sort of update from the maker.
