Yes someone's mentioned it already IIRC, it's a possibility.
Possibly based on their dual core version mentioned here:
http://en.wikipedia.org/wiki/Rockchip#RK31xx_series

I really doubt thats even possible, many hw manufactors does not even give out full techspec for theyr hw that makes it impossible write open drivers!

Now thats why libhybris exists... Because even if Canonical/Jolla want native Linux drivers they can't write them and instead have to use closed Android drivers. Remember that open plasmatablet? how much problem they got with hwmanufactor...

Especially all those new asian companys are bad on writing techspec.

Is it 100% confirmed that jolla won't can/will release a real qwerty as other side?

Can the OS run in landscape med atm, otherwise it's an indication that no keyboard is imminent.

My guess is then 3066 with Mail400(means will probadly depend on libhybris) or 3168 with PowerVR(SGX no need for libhybris AFAIK)

They said at one point that their focus is on portrait, which is a pretty good indicator what their immediate interest (at least) is. That doesn't mean they won't eventually focus much more on landscape, or make it easier for others, or that Nemo won't focus on it. It doesn't make much sense for it to be a priority right now, given that they're clearly launching w/a slate device. But who knows what'll happen not too long after launch, especially if the "Other Halves" are not just NFC triggered sw auto-runs, & can also do hw augmentation in which Jolla releases their own "Others Halves", or does so with partners. (But the latest speculation is that "true hw augmentation" is probably unlikely)

for anybody who cares about X11 , i had a chat with stskeeps on irc and he pointed out that xwayland and xmir don't support opengl/egl. how many apps that affects i don't know. things like openscad are affected for sure.

i thought that there was no landscspe mode, but someone corrected me and pointed out that the alpha sdk has support for landscape mode. maybe someone can confirm this is still the case for the beta sdk?

It has landscape support, they just won't use it in many apps.

Landscape mode is essential for the browser and e-reader for example.

Yep, which is what I was getting at by saying "it's not their focus"...
There's always some apps that naturally work better in landscape, so it makes sense to have a basic lvl of support.
