So lets talk about WHERE this tour could possibly visit, and how many shows? Assuming it'll be in stadiums.
Auckland x2
Sydney x2
Melbourne x2
Perth x2
Adelaide
Brisbane (not sure if they'll do 2 shows here, the 2nd one in 2010 didn't sell very well)
Japan x2
That's 12 shows. Where else? Coldplay did Bangkok, Taipei, Singapore, Manila, Seoul, Tokyo, Mumbai and Dubai on their Asian Tour, in stadiums/stadium sized venues.
