Noggin's right. There was never any suggestion of a 2235 closedown - this is wilful misreading by the press or wishful thinking by a certain kind of anorak.
Indeed it's been made clear that "important" programmes after 2235 - Newsnight, Question Time, Imagine - would not be affected. Add on a few things like Norton which are popular and bear in mind that BBC2 usually shows repeated programmes at 2320 and you wonder how much content on the major channels is directly under threat.
More realistic is the chance of Sign Zone and handover to the news channel being brought forward to somewhere between midnight and 0030 - in other words what was closedown time until the mid 90s. Then take a look at next week's schedule. BBC2 often goes to the News Channel now about 0020 on weeknights and Sign Zone seems to be creeping forward anyway.
