Considering Vera Lite and Vera 3 were still being sold well into 2015 I don’t think it’s right to say that these are obsolete.
You also have to consider that the difference in specification from the Vera 3 to the Vera Edge wasn’t much in terms of CPU, memory and used flash partition space, so from a technical point of view there doesn’t seem to be much of a reason that this new interim firmware can’t run on the old hardware.
I can certainly understand customer frustration when they’ve been patiently waiting for 8 or 9 months for a new firmware release, to fix bugs and issues that in some cases have been present throughout the entire UI7 history and to only now be told that there’s no firmware for your Lite and 3. I wonder how many Lite and 3 users have support tickets with the phrase “this will be fixed in the next release” in them!
IMO if Vera’s position is that Lite and 3 are obsolete then that should have either been made clear back in July last year, or should have been expressed after this firmware release and then with the newly “ground up” developed firmware that @melih has been touting being announced as for Edge and later only.
Although even then, there’s nothing concrete been committed to here either, unless I’m mistaken, as this new series of firmware has been stated as for the new Ezlo hardware only in the first instance, and legacy Vera hardware “at some point later”.
As it stands, everybody that has been holding their breath for fixed firmware for the best part of a year now has to make a choice - do I upgrade my Lite or 3 to an Edge / Plus / Secure just to get this new interim firmware, or move to a new platform? And if I do upgrade, what’s to say that my new Edge / Plus / Secure isn’t then obsolete in a years time when Ezlo suddenly decides that the new series of firmware actually isn’t going to be released for existing hardware after all.
Vera has a long history of broken promises and poor treatment of customers, sadly with this current move it seems that this is continuing.
