They already earning money now selling multi figure content. So why do they need their own figure if they already making money just selling content, be it for Daz only, Poser only or both?

Because V4 is getting older for one.  For two, DAZ could decide to stop selling V4/G2/anything that can work in poser and poser users don't need to be at the mercy of that one company.  About everyone I've talked to tells me G3, ie the newest figure, doesn't work at all in poser.  For 3, poser can do things like weightmapping that I don't believe is possible in DS.  For 4, if there's no new products for poser users to buy then rendo's poser userbase will stop buying here and that's going to hurt the bottom line.

DS does weightmapping.
