In 3/10 report from Hana Financial Group (download here), expectations of SM artists concert mobilisation in Japan for 2017 were revealed, with TVXQ coming on top!
The bar chart shows TVXQ (in dark green) in 2017 with a bar length that is comparable to that of 2013 which had a total of 893,000 (cr: Nikkei Style)!

This figure probably includes the numbers from the one-month long TILL2 tour, but it is not a huge number, so fans are speculating on how big the upcoming tour will be~
