How long will Max10 Devices be made?

I've designed in the Max10 part on two designs recently, these are great parts. Particularly running Nios with several functions in the fabric. The customers have been very happy, and they are asking how long these parts will be made by Intel? For example, is the window at least 5 years?

Any information on this is much appreciated. The cycle time of parts turning over is getting quicker! So this is a legitimate question from a customer.
