Hello! This is my first post. It seems like you guys have a wonderful community

.
TL;DR Edition: Given the history of Kobo's release cycles, is now a bad time to buy a Kobo Libra H2O?
Unabridged Edition: I've been reading ebooks on 6" Kindles for the past 6-7 years. I own two at this point, an older base model and a newer Paperwhite. I'm interested in seeing the potential advantages of a 7" reader. The Libra H2O interests me for three reasons:
- I'd like to see what it's like to read on a 7" e-reader
- I've never owned an EPUB e-reader before
- The cost barrier to experiment with a 7" e-reader is lower with the Libra H2O than with the Oasis
I know Amazon has had a fairly regular release schedule, releasing one device a year and whereby it takes three years to refresh a given line.
Does Kobo do something similar? If not, is there any reason to expect that there would be an imminent refresh of the Libra H2O?
Thanks for reading my post!
