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.
