How long is the technical support for the TX2/TX2i product?

I saw the below site of Ketson product lifecycle

Is the TX2 / TX2i HW / SW technology support the same as the product lifecycle?

Hi baekwon.choi,

The L4T SW sustaining releases for TX2 / TX2i will continue to be made as deemed necessary.
The support will be longer than product lifecycle, as you can see we’re still supporting TK1 now.

May I know what’s your concerns?
