OK, perhaps some more tendency for macroblocking than in the uncompressed - but edge definition, I expect to be equally good.
What I don't understand is how nanoFlash (or other) will be able to feed a compact flash card (or even 4 of them at the same time) with a 100mbps data rate... If it would have been so simple, why would Sony use SxS ?
I think there is some kind of mistery here...

Who knows what Sony's reasons really are?

My opinion? Fast enough CF technology wasn't ready when the EX was being planned for. Sony wanted a card format that would work with mobile devices drectly at max speed. There is a progression from PCMCIA/Cardbus to ExpressCard as well.

The interface is more than just a "memory card", making additional options possible (PHU-60K, maybe even eSATA later on). And I also believe Sony wanted a "Professional" solution for which they could control the media quality (although by using the USB interface for the PHU-60K that seems to be out the window).

Anyway just my 2c.

SxS has other advantages. SxS is very fast so it has plenty of head room for future development. It is very difficult to corrupt the file structure on an SxS card. Pull one out of the camera mid-shot or remove the power from the camera mid shot and the most you will loose is the last 4 seconds of the shot.
