Wirbelstrum,
Your information tells me that you are in BA, so I know what you say is correct. However - it was the last but one recruitment campaign that ended in 2006/7 that the last DEPs went onto the 777, and if you look closely at the latest Cassandra run you will note lots of soon-to-be-unfrozen bids for the 777 in 2012 training year. Therefore, can't see any DEPs going onto the 777, 744 definitely (including A320-rated guys/girls)!
But as you say, never say never. Good luck to all in holding pool/selection process.
Cheers G777
