Quote - I would like to know were you heard about it.
The Carrara SDK is free. The Poser SDK isn't free last year  I was told by Bob Stockwell that  it was around 15K but I am not sure about the actual price.
Switch from Poser to DAZ Studio I am not suggesting that at all.
 Carrara can load and handle poser type content in what is know as Poser Native format and that is the  format that will be expanded or improved in Carrara 6. It means it won't be handle like in Bryce .:-)

 
15K!!!  Man EF is really sufffering from a case overestimated self importance.  I wish these software companies would knock it off, grow up and start behaving like adults.  They need to work together and not fight like kindergarteners in a school playground.  Hopefully DAZ will figure out some way to get poser support back in.  Maybe a conversion program which will turn them into a .car file.  That would be cool...
