USPS has it. If they do their job, chicolom will.
I'll admit, the craziness at work and general transportation issues I've had on my off days set the ship date back a week longer than I intended, but it's finally moving along.
OnePunch, eBay is your best chance. If you like Dolby Headphone and chat mixing, the older Mixamp is your best shot. Minus the chat mixing, you can save a lot of money buying a Turtle Beach DSS. For something in-between that uses THX TruStudio Pro instead of Dolby and can also double as a USB soundcard for a PC, another solid option is Creative's Sound Blaster Recon3D USB, which NamelessPFG is trying to sell for $70. You can't mix chat using a DSS or Recon3D, BUT if you're playing CoD and you have a mic directly plugged into your Xbox controller, if you want chat audio louder you can turn UP the volume on your surround processor and DOWN the game volume by hitting start during a match and going to Options.
I probably should sell my AD700 cuz money is tight and I have the Q701, but...
Except you CAN mix in voice chat using a Recon3D USB with both the X360 and PS3. There's an extension cord with an additional port that connects to an X360 pad's headset port, and the microUSB port that powers the whole thing also handles PS3 voice chat. The Ear Force DSS bafflingly offers neither option, to my knowledge.
The catch is that you can't adjust the game/voice volume ratio from the device itself like you could with a Mixamp, which is a strange oversight given that they've come this far already.
