Not that I know of. But that's my point -- it's not really that big of stretch to go from Kobo Aura 1 pushing the light evenly 7 1/2" up from the bottom*, to pushing it evenly ACROSS the less than 8.8" of the Sony device. Obviously it will require more LED's, but I don't see that really being anything other than a battery issue.

* - any significant blotchiness on the KA1 seems to be with the red lighting, not the basic "normal" lighting.

That's plausible, but the frames of current small devices aren't completely rigid, so there is obviously some tolerance for flex. And I can't image the new devices flexing that much more (albeit the deflection across the larger device would be more) under normal use.
