Actually, that's quite possible.
Back in June 2003 when the "Renewal" set came out, it was sold out relatively soon afterwards. However there were also single-volume releases (
which are still in print to this day) announced well in advance and sold soon after the box went on sale, so the only thing that couldn't be easily bought after the box went OOP was the 11th bonus disc. Below is the schedule of the 2003 DVD releases that was announced in December 2002:
Mar 26, 2003: "01 Test-Type" (a disc with just Episode 1 to show the A/V improvement in "Renewal")
Jun 25, 2003: Renewal box set w/ 11th bonus disc
Jul 21, 2003: Volumes 1 & 2
Aug 27, 2003: Volumes 3 & 4
Sep 26, 2003: Volumes 5 & 6
Oct 22, 2003: Volumes 7 & 8
Nov 27, 2003: The Feature Film (i.e. "Revival of Evangelion" in a 2-DVD package)
Eventually there were re-releases of the 11-disc Renewal box set (both a reprinting of the full 2003 box with the fancy "monolith" box and booklets, and a price-reduced "07 Edition" thinpak box with just the discs themselves) but it took a full 4 years (August 2007) for those to happen.
All that said, Khara / King Records have to date made absolutely no announcement regarding any future single-disc Blu-ray releases. As such, it is somewhat plausible that the 2015 Blu-ray box and/or the "Archives of Evangelion" DVD box may be in print indefinitely. But I wouldn't postpone buying either one if at all possible. It's always 100% harder for foreigners to buy Japanese media on the secondary market as compared to standard retailers like Amazon Japan and CDJapan.
