It appears Rendo/Bondware has decided to rationalise on one version of Poser only. so there is now only Poser Pro. I can see this makes sense in trying to get all users to be using the same version, so for example someone making a body morph for a figure for sale no longer needs to worry about clothes fitting as everybody has access to the copy morphs from feature which used to be a pro only feature.

I can't remember the base price of Poser 11, but I know I paid more than 199usd upgrading from Poser2014pro to 11 pro. And now if you buy Poser 11 pro you get extra content that is available in the store to the value of 900usd (according to Rendo, I haven't checked it myself).

Also you can download Poser 11 pro and use it for a 21 day trial for free.(but you don't get access to the extra content until you buy it)
