Confirmed: No June shutdown, not that fast.
Current product can sell for years, next product is on the shelf, no hurry to come out new product, no too many buyers anyway.
Arch hits the wall, high power/frequency/cost but no obvious performance advantages.
Current project is a place holder, won't last long. No points to spend big money building a product for a discontinued OS and limited customers.
A smaller team with limited budgets will remain for future arch development.
