If cisco really is moving towards SIP as claimed earlier, then releasing 
new phones which are sccp-only is a step backwards from that goal.

If cisco really is moving towards SIP as claimed earlier, then cisco 
should release SIP images for 7970, as they did with 7960 and 7940.

This only means sccp is currently better for cisco phones, it doesn't mean 
sccp is a better protocol.

sccp and asterisk has some err.. real annoying bugs at the moment, where 
ciscos running SIP don't have these problems.

Given a choice I'd run SIP, if only to have the phones able to talk to 
each other and gateways if the PBX dies for any reason. sccp can't do 
that -- if you lose the PBX you totally lose all functionality on all 
your sccp phones.
