Man , ya gotta love this thread.  started out on V4 and now we're discussing something approaching the mathmatic formula that solves everything.   

For what it's worth:  Daz and its vendors will continue to support what ever makes Daz money. 

If they believe that V5 (or what ever it will morph to) will outsell V4, then they will go in that direction.

BUT!

Anyone out there remember IBM and Micro Channel Architecture.  Greatest thing for PC's, better than the just plain architechture that most peolple used, but only on IBMs.  IBM demanded royalty fees to use their system.  No one wanted to pay so the other guys used the slightly slower one and now the question is..........How many of you are using an IBM right now?????   (let's see 1.....2...3.. that's all??)  

If Daz continues to go in an excusive direction, they may be right up there with IBM.

Just an observation.   (and I didn't even get into the V4 v"ersus" argument).

I use whatever seems to work, even V2 (great for backgrouns)
