Kobe is on longer that dominant Kobe. Bynum as the untouchable young "prospect", his health and durability is not going to improve much. Gasol will still be very good, but the new CBA cap won't allow them to keep everyone. Without Odom and/or Bynum or Gasol, even with DH13, I don't think Lakers is not scary.
That being said, what if DH13 goes to Knicks? Then it depends on how long Billups can play. If Billups can last the whole season and playoffs, watch out.
If Dallas gets Butler back, and resign key FAs in Tyson and JJ, no one can count them out.
Also, what if DH13 does sign and trade to Heat for Bosh?
Anyways, NBA gets more interesting.
