I'd say its a game changer in that they are changing the game that they are playing at.  Its a full scale retreat from the software & content game back to the content only game that they are comfortable and successful with.  Their problem this time around is that they tried to bar people from their content without adopting the software.  Clearly that did not fly so they have to hope free is low enough price to get people using genesis and investing in v5.   This should help them some, but you wont know it has truly failed until you see them 'miraculously' release a v5 figure subdivided to an acceptable level and rigged to work(by daz standards) in poser (likely with the old style rigging but maybe WM also)

 

Quote - > Quote - It is a game changer in this corner of the CG universe. Those not decided about which software to use can get DS 4 Pro for free for 29 days. Poser Pro 2012 won't be free. Easy pick for most people in these tight times. And anyone wanting to try the Pro version will now have all the regular Pro features to play with. This will substantially increase their user base and gain them more folks wanting to buy content which is still their main business.

And I would bet that previous purchasers will get the future 4.1 release for free or reduced price (it's the version with the big render speedup). The freebie folks will have to upgrade for the render joy. That's my guess for the future.

I read your statement five (5) times. I'm very thick. I fail to see how that's a "game-changer".
