Barry, I'm slightly indifferent towards big hops and Belgian yeast. Punk Monk is great but there is something jarring about Raging Bitch for me. give it a go and i'll happily drink it though!
Chunk, that does sound pretty good and it would be nice to see something different from Brewdog. however, citing Watermelon Wheat is a bad example - it's pretty horrible (although all the other 21A beer are great!). The big stout isn't exactly a summer beer either, but hey, it sounds good!
Tandleman, I agree. when they get cask right they can be very good. Trashy Blonde in Spoons was delicious and cask zeitgeist can be fantastic. I would like to see 77 a little wider.
Rob, they've never done a coffee and coconut imperial stout aged in rum barrels 
That barley wine sounds good, although I wasn't keen on the latest Mikkeller/Brewdog Devine Rebel. I'm very towards seeing them do something refined, to be honest, not smack-you-in-the-face with flavour (despite calling for the beer I am!!).
Sid, maybe they could package it in a 750ml champagne bottles too? in a nice box...
