The fact is that some of the new keg products are very good but hideously expensive. The distrust and rejection of anything keg from older CAMRA people (like myself) comes from the horror show that was the big six keg beers from the 1970s. As far as I know none of those beers still exist. In my limited experience of drinking new keg beers in the Leyton King William IV before the prices went through the roof, the stronger ones tend to come out better as the chilling makes them easier to drink. On a very hot day the keg can become more attractive.
Personally I think that the new brewers are only putting stuff on keg to increase their profit margins.
I had Dark Star Revelation earlier this year and can't imagine why they should want to keg it. The same goes for Jaipur and Siren Broken Dream.
