Updating a tablet from 4.3 issues

[telfish]

I just bought a brand new Nexus 7 16 GB wrapped in it's plastic unused. Charged it turned it on, as expected it's on 4.3.

Problem is when I check for updates it says the tablet is up to date and will not update to 6.0 which I believe is the latest this tab will go to.

Question is will this self correct if left on or will I need to manually update using OTA update from a PC. Also if I do need to manually update will I need to find and install every intervening update between 4.3 and 6.0?

I wouldn't wait for possible OTA updates, which would probably be incremental even if they did come through. I'd go straight to flashing the final build, which will include all previous updates.
