What is your actual time-line?
ST is already working on newer devices, expect the team that built it is on to other things.
The business is predominantly a built-to-order one these days, and distributors don't have deep stock.
If you have long term expectations you would need to stock-pile or warehouse enough parts to reach your own commitment horizons.
ST will keep building things provided it makes business sense and the production/test equipment are available/viable, beyond that you'll have to pay market price to those who did hold inventory.
