I don’t speak much Russian (I know exactly two words thanks to Red Alert 3 and the likes of it); but the above image posted by Nokia apparently is an invite to an event to be held in Russia on Nov. 6th. If only one of the two new Lumias is to be announced then I’d personally place my money on the 920 seeing how the invite shows a camera and a bat (infamously nocturnal creatures = Night-time photography). Hopefully we’ll have a clearer picture of the pricings and availability date before then; but November ain’t far off now (interestingly enough there still seems to be a fair bit of buzz regarding the new Lumia line-up even though they were announced over a month ago- hopefully that’s a good omen).
In case you’re interested in pre-ordering a white, Yellow or black 920 in Russia MTC (Russian carrier?) seems to ahve them up for pre-order along with free delivery, but no expected arrival date:
