Discontinued Forma a viable option?

I am considering the purchase of a Kobo e-reader. I had a Nook HD+ years ago and I prefer reading from a larger screen. I’m not interested in listening to audiobooks and doubt that I would take advantage of the Sage’s note-taking abilities. It seems like the Forma best fits my needs (Libra 2 has smaller screen yet weighs more) but I am concerned about lack of updates/support going forward. Given Kobo’s history, what is the best guess for how long Kobo will continue to support the Forma?

TIA!
