Thankfully a bit more low-key than the 'triumphant' opening of T5 in 2008!

Yes, they're sensibly phasing it in gradually over several months. I'm not
sure of the plans for T1 after this -- some of its gates will be
transferred to the new T2, but I assume the rest of T1 will then be rebuilt
in phases. I think it'll all be called T2, leaving T1 as the number for the
new terminal for the third runway.
