No more Rock Band for me for a while. I lost pretty much everything.
Writing from a hotel room on a computer I was able to rescue.
The XBOX, 2 Mustangs, 2 Keyboards (one that I customized), MPA (also customized), Rock Band 3 drum set, 2 Rock Band 2 guitars and well pretty much everything I own was destroyed.
Hopefully once the insurance company sorts through all the wreckage I'll get a new system and replace as many peripherals as I can.
