Lollipop image is up:
https://developers.google.com/android/nexus/images
Flashing the image now, let's hope ART improves this tablet by a good bit.
Another note... I have to drain this tablet to 0% every time, otherwise the battery problem crops up again. At least it properly goes to 0% now instead of the previous 40% before it died

.
EDIT: No translucent navigation and status bars. They work fine in custom ROMs, I don't see why Google still feels the need to have this disabled on the N10. Moving away from Thunderkat makes the homescreen look horrible

. Hopefully the developers will get root working on this soon, and hopefully the ART version of Xposed will be out too.
And the notifcation area too, it feels weird not being able to swipe on the left side for notifications, and right for the toggles, but I guess they wanted it to feel more uniform with the phones. At least 2-finger swipe still works for toggles.
I miss my lockscreen widgets...
On the other hand I'm surprised I'm still seeing around ~400mb RAM usage, seems to be as light as Kitkat, I was expecting it to use more considering the massive changes but it seems Google has done wonders on ensuring it stays small.
