Will Saber/Archer banners go away in 4.4?

Hello everyone

I was wondering if we have any info about Saber/Archer banners staying or going away in 4.4, since I am saving for E2S1 Rin/Gilgamesh, but I still wanted to get S5 Saber (She's E6S1) and Archer E2 (He's E1S1) but I was planning to pull them after Rin/Gilgamesh pulls.

For me it would make sense for the banners be there at least for a bit more since we are getting a teammate for both Saber and Archer and people might have skipped Saber or missed the free Archer. Yes I know we will be able to pick between a free Gilgamesh or Archer
