I don't think we have seen the changes that were heralded in the Guardian interview. Had it not been for that piece I suspect that the changes to the studio and a couple of the angles would have passed without comment (well, perhaps not without comment on here

).
Also, the plasma screen appeared to be shown for the purposes of that one shot. I don't expect it to become a regular part of the furniture.
A long standing bugbear of mine is that I think far too much is made of the fact that the presenters stand at certain points during the ITV News, (and there is a similar fuss regarding the BBC News for that matter). Usually they will only be seen standing at the start and end of the programme, and possibly either side of the commercial break, with walking limited to the walk back to the desk at the end of the programme. Hardly a whirlwind of activity.
It's not like Sky News where they make a feature of having presenters stride from one part of the studio to another.
I suspect that if the whole half-hour bulletin was to be presented from behind a desk, once it had been forgotten that that's what has been asked for in some quarters, people would comment on just how static and uninspiring an approach that is.
