Apparently the NJPW/ROH crossover show last year made basically no money, so it'll probably be scaled back a bit this time.
I wouldn't at all be surprised to see ticket prices go up this year. I went to the NYC show last year largely due to tickets being $20 for still pretty good seats. When I went last year, Wrestle Kingdom 8 was basically the only recent NJPW show I had watched other than some clips and I really don't have much interest in ROH. Being more into NJPW now I'd gladly pay double that.
