How are tickets going for the NFL London game next season

Just a little FWIW, I wanted to know any information on how things are being prepared for the London NFL game this upcoming season in the UK, I had heard that you couldnt buy a ticket yet in that country for the game and that it will be a huge marketing bonanza on the NFL and the British Media in general in the weeks and months leading up to the game.

should be interesting to say the least, thats for sure
