Trust me guys - I'm as curious as you are - !!!
The only thing I know for sure about the back is there are continuous wood plates covering the electronics. Beyond that, it's a given that whatever else there is to see will be awesome.
It is supposed to arrive today (pant, pant, pant), so I'll snap some cell phone pix of the back and post ASAP.
BTW: I passed the audition the other night, so she's gonna see some heavy use very quickly. My task this weekend will be to ensure she's ready to hit the ground running.
