I'll say this much, I'd much rather have some time on the 320 in the RHS rather than going into a command on the thing with no experience on it. To each their own, but I reckon it's not all bad on the 320 and folks could be doing themselves a disservice in the long run by avoiding it. The other thing is why the heck would you want to do 11 years in the middle seat before a chance of an upgrade to a window seat long haul?
As to the rumour, yes there could be entry direct onto the bus sometime this year.
