Hope something changes tomorrow when they're finalised, are the slots TBA or filled with other shows?

There's no reason why BB can't launch that week because of BGT, that reason isn't good enough. There's no live shows that week (other than The Voice's first one on Friday, which they would obviously avoid) and with the final on the 8th, all they need to do is ensure Saturday's highlights show is at 10pm, and actually then they could capitalise on BGT's audience who are changing channels.
