Dan did say over at the DAZ forums that they would be supporting Poser 6. (And there was much rejoicing!)

I don't think they are enemies. However, I think a certain amount of tension is inevitable, if only among the users. ;-) Time and resources are limited, and DAZ will no doubt be juggling support for Poser 6 with support for D|S, Bryce, etc. It will only get worse if Poser 7 has a new rigging system.
