Kobo's next ereader has shown up on the FCC website, but unfortunately that is just all I can tell you about it right now.
According to the paperwork, the Clara HD is going to be made by Netronix, just like Kobo's previous ereaders. Judging by that one screenshot in the paperwork, it will have an E-ink screen and Wifi, and it will run Kobo's software.
Unfortunately, I cannot tell you the screen size or whether the Clara HD will be waterproof. But it's worth noting that Kobo's last ereader was the 6.8" Aura H2O2, and before that they released the 7.8" Aura One, which suggests this is a 6" model.
I can't even tell you the launch date with any certainty (the embargo ends in September, leaving a long possible launch window).
But I can tell you this first of April that Kobo has a new ereader coming.
I can't wait to see it, can you?
