Why they say ITV is getting a new look in the autumn and they do it July puzzles me. I always thought the 1st of July was the height of summer!
There will probably be a new trailer design on 1st July, the current one has been used since the introduction of the ITV1 branding imho, they don't usually keep them as long as that.
I think it's a definate possibility that the ITV1 name might disappear again. On the new look ITV.COM website in their regional section they show all the dual-branded station logos in the original 1999 'just ITV' style.
ITV1 will probably be the eventual name of the channel when it becomes 1 single channel but atm the old station names are still just about the dominant brand in which case it's rather silly to use ITV1 as a channel name when ITV1 as a channel doesn't exist yet.
It's also especially stupid to have an ITV1 when most people can't get an ITV2 to go with it.
And as I've said before, ITV(1) and ITV2 have a UK Gold-UK Gold 2 type relationship, in which case there isn't a case for having anything other than ITV and ITV2. They DO NOT have a BBC1-BBC2 relationship, and until they do it's not really appropriate to try to emulate that (which at the end of the day, is exactly what they were trying to do, whatever crap they may have come out with about it reflecting their move to an integrated channel provider).
