You might notice something. Soon.
I wouldn't be at all surprised if it's only something like a minor tweak to the sunrise view shown on the "windows" (e.g. the removal/replacement of the "glitterball" vertical banners, but the rest of the view being totally unchanged) or whatever, which average viewers won't even notice.
Something as substantial as e.g. a proper full set change would be lovely, but I've long-since learned to have very low expectations of any mooted changes to Breakfast. It would be nice to be pleasantly surprised, but I'll not be holding my breath.
I'd hope for the presenters sake that a new sofa is in order - even if it is identical.
