I couldn’t say for certain, Dodoso, Customer Support has no involvement those kinds of decisions so we wouldn’t have any information on realm population or what may be done to help low population realms.
We did have realm connections for Classic Era realms in May. There may be more coming, but generally, our Developers would wait until things settle between Classic Era and Burning Crusade Classic before making any additional adjustments.
Any such announcements will be made on the Classic Era discussion forum and I’d recommend any discussions on the subect would be better suited there.
