Many people, including in this blog's comments, on MobileRead, and on other blogs, have been remarking over the past few months that the Kobo Aura One is rarely in stock. Kobo's largest ereader might show up on the website for a few hours, but then it quickly sells out.
While we still don't know why this 8" ereader is out of stock, there is some light on the horizon. A little bird has tipped me to the news that Kobo's next ereader was mentioned in the latest update.
The v.4.3.8871 firmware update includes a reference to the "Kobo Aura H2O Edition 2" ereader, a device which does not yet exist - not even on the FCC website.
The Aura H2O Edition 2 is the replacement for the Aura H2O, the 6.8" ereader Kobo launched in August 2014. We do not yet know the screen size, but it is safe to assume from the name that Kobo's next ereader will be water- and dust-proof just like its predecessor.
And based on Kobo's history of launch events, it is also safe to predict that we're going to see the new device in either April or August.
So if you are planning to get a Kobo ereader in the next couple months, pay attention to the rumors for the chance to be one of the first to get the new model.
