Spring? That strikes me as unlikely. The KS8s came out in February or March of 2018 and they’ve been on roughly an 18 month cycle. I’d guess August at the earliest. What info do you have?
Also, the “pattern” has been for $100 price drop with each new model. KS6 was $1799, KS7 $1699 and KS8 $1599. Nothing says that pattern will continue, but it’s a possibility.
