Thanks for the link (and the link within the link 
). There are obviously still some issues that need sorting before moving to Windows 8 becomes an attractive proposition.
iLok and Waves seem not to do well after the move. Waves, I sorta suspected but iLok? Ouch! Now that would be nasty. 
PCI here so dunno about Firewire but understand your concern.
Wait and see seems to be the way to go?
