I just received the following rumors form a good source. I hope other sources can confirm that soon:
“And an update: I can say that there maybe an DSLR alongside the A77, A7XX. Just like the A580 to the A55. And to clear the other debacle up: You can either have:
CF
CF+SD
CF+MS
SD+MS card
SD card
MS card
”
REMINDER: The A77 and/or A7xx will be announced early 2011. At Photokina we will see a mockup only!
