I think that the said that he was spending the next two weeks *just* catching up on existing orders through the end of april. He took a lot of pre-orders, there was a huge response, and I can imagine that he now has to process, assemble, pack and send hundreds of orders.
as a result, my guess is that everything is off to the side until the first week of of may. So I wouldn't panic and I'm sure you're not being ignored. Give him some time and check back in with him then.
