As a follow up: I got pretty excited when I received a package this week but it turns out it wasn't SSDs at all.Yeah, I figured it had to do with that. I just did a quick look around for the 1 TB drives (m500/840 EVO) and both seem to be in stock in just about every store.
They haven't shipped and I'm going to cancel my order in the morning. I'm going to try and have family that are visiting the US pick a couple up from a Microcenter or something while they're there.
The retail price on Amazon has increased by about $220 from when I ordered too (not that it matters, but I saw the same thing with the Crucial disks and it leads me to suspect another paper launch).
