i recommend doing a wipe before, although, i was able to flash it without wipe (cominig from my hellybean rom)
please make a nandroid before!
this is a good summary:

Hard to manage things once on the pre-Alpha with no access to sdcard so prepare your backpack lol,i had chance i already had a CM10 apns-conf cwm zip on sd.
From recovery only sdext is mounted via usb but it's still a way to push flashable zip/install from ext.On running device Mtp gives no error but mounts nothing.
I came no wipe and my apps was there at first boot but disappeared after a reboot.
Root was a problem too apparently,i didn't had much time and only tried to put busybox in /system/xbin but didn't worked.
I'm saying all this just for those wanting to give it a try to be prepared,make arrangements before and then maybe extend their test
