I would think, like a computer that has become a bit obsolete, the same goes for M1. Most people like the higher "abilities" of M2 and M3. I don't think DAZ is pushing anything. I just think that most people want a "higher" model and accessories to go with it. Having said that, I would still think there is a market for M2 stuff. People who don't have the money to get M3 (and the assorted wardrobe), a powerful enough PC, etc. As said above, Poserworld ($50 yearly subscription) seems to be supporting multiple models with their clothing releases. Check it out. And, browse some other sites. And remember, most items on DAZ are brokered. Not sure of the policy, but I suspect the brokers get to choose what they want to make and sell to a large degree.
