I don't think it was announced.
I wonder if the contract was for the 30 weeks (as per previous series), and they extended it as it would be the last one at a later date, she may not have wanted the move every week, wasn't she newly married at this point? A shame on the timing and being up against Ant, Dec & Cat because Katy was very good in the role as was Trey
Wasn't she newly married to Trey though, so by not going to Glasgow they'd have been apart more.
She wasn't - she had been married to a childhood sweetheart for a couple of years. This marriage ended soon after and she married Trey after that.
Now, you could put two and two together here and speculate on why she decided not to continue being part of the team, but I suspect the truth is probably a bit more boring, that the show was on the way out and as the biggest "name" on the presenting lineup she didn't need the work as much as the other three, so decided to make the jump at the end of the initial contract.
The decision to run all year round was taken after the start of the series, but before the axe came. It was when Nigel Pickard arrived from ITV and decided to make Saturday mornings and Blue Peter run all year round as it had been very successful with SM:TV. The axe fell in March (http://news.bbc.co.uk/1/hi/entertainment/1231028.stm
) but this was only a few weeks away from the end of the initial 30 weeks and extension to summer months, which had presumably always been planned to be in Glasgow for reasons outlined earlier.
