Okay so in the next week trailer you can CLEARLY see Triple J (or atleast two members) AND Times Red in Vegas?

I heard about Rough Copy being booted but why are TWO groups back? Have they merged Triple J with someone else? Because in the clip I froze there's four of them performing.

Yeah they added George Shelley and now they've become Union J? Apparently.

Why did Rough Copy get booted anyway?

couldn't get a visa to travel to america apparently

That just makes it doubly confusing... Why add another member to a polished band already that the Judges all apparently already like :S

Actually it's due to one of the members being born in Nigeria and having his uk visa application processed. There were fears that if he left the uk he wouldn't be allowed back in.
