Sadly Amazon is notorious for not updating older models. (Owner of a paperwhite and original kindle fire). I guess that is a motivating force to upgrade (new purchase). I'm indifferent on the new hardware, but the software tweaks are really compelling...

It took several months, but Amazon did a major update to the Kindle Touch to the Paperwhite-like interface. I think it's likely that the old Paperwhite get the new updates.

Are you sure it's all marketing? I mean, what developer wants to target twenty different platforms?
