Chess cafe has a nice review on Fritz 12:
http://www.chesscafe.com/Reviews/review709.htm
Its a neutral review for the most part, more for informational purposes, rather than a critical review. Athough the writer was clearly impressed with the new version. Its only compared to earlier versions of Fritz, so not really a critical review in my mind. And he definately not comparing the strength of Fritz.
Since its been a years since I bought a chess program, I might end up getting Deep Fritz 12 when it comes out. Last Fritz program I bought was Fritz 8, lol. I do have a more current copy of Chessmaster, but truthfully I didn’t see much difference between CM11, and CM10.
Chessmaster 11 has some new training material, but not so much I feel like CM11 was a must buy over version 10.
I get the feeling Chessbase is selling Fritz now based on improvements to the interface, and other stuff designed to help a person improve thier play, akin to Chessmaster’s long standing tradition.
There will always be a market for “best engine”, but right now, other engines like Rybka and Shredder are taking that lead. For the vast majority of players, Fritz 12 might be a good investment over earlier versions of Fritz, if only for the redesigned interface.
Chessbase sells Rybka and other really good engines, so they might just not feel a huge need to market Fritz based on strength now. I predicted a while ago that Chess enging -vs- Human matches were all but gone, and thats pretty much a given now. Maybe Adam’s match was the straw that broke the camel’s back.
Even before that, it was getting harder and harder for developers to even find a qualified GM to put thier reputation on the line in a man vs machine match, and that was a few years ago.
