I'm a post-Apothcolypse webOS convert. I've always said LG is the one company I wish would take up the webOS operating system and make hardware for it. Honestly, this is not sucking up. Check my post history.
I'm sure all has not been revealed yet.
I don't expect any movement on that front in 2013.
But Google's pledge to not favor Motorola with first release of versions is running out. LG committed to a FireFox OS phone and so did a lot of other players (Alcatel OneTouch, ZTE and Huawei) so that is already a crowded field.
The Nexus 4 was an honor that keeps LG with Google for a moment, but where will the next Nexus come from? Motorola???
webOS is way more mature and field tested than Tizen, FireFox, Ubuntu, etc. Sailfish might have a claim at maturation, but the Chinese OEMs have gotten hold of that one.
Let LG's people start playing with webOS and see how it starts springing up throughout product lines. I wouldn't rule out the mythical webOS toaster... Nor would I rule out a webOS phone or tablet.
With webOS, LG now has an in-house OS with a smooth UI and huge connectivity potential. Once it gets into homes via TV (+ its remote), dishwasher, refrigerator, whatever... Then the time is ripe yet again for handsets and tablets. The UI is back out there and getting an audience. webOS does need a revamp and a rehabilitation in the eyes of the consumer market.
