This was a really special deal and it might happen only once in between V Collection releases, that too when a new V Collection release is around the corner. So, I would expect it again around next Black Friday assuming V Collection 10 is released in December 2023.
EDIT: Sorry, I messed it up a bit here. While the $49 crossgrade for Pigments is certainly a rarity, the above sale was actually the reverse, where Pigments owners got a crossgrade offer of $149 for V Collection 8, a couple of months before V Collection 9 came out in May 2022.
