Quiet Panic sent out an update through Bandcamp on Thursday - "Just to keep everyone in the loop, we've experienced some production delays with both the Tennis System & Slow Crush LPs. We hope to have them out to you soon, but it looks like it will be at least a few more weeks, if not longer. We apologize for the delay and will let you know as soon as we have a firm date for shipping."
(and I keep a spreadsheet for pre-orders, too, including a column for street date and a column for notes like this)
