No, sorry, nothing regarding this was improved in the new firmware.

You are talking about 720x576x2x25 or about 20 MByte/s which 
you would need for transfering complete pictures in real-time.
I don't know how high we could really get. Right now we are happy
about 20 MBit/s.
It would also create over 5000 Interrupt/s on the PC side even 
if you use the full 8K dual ported RAM with buffer switching 
for transfers.
