Apparently every match at the G1 Chicago show is going to be an actual G1 match according to the US site.

So now I wonder if it's both blocks wrestling on the day, or if we are getting a larger tournament this year with like 14 per block and this is still one block.

If it's the first that'd be something to see considering some of the NJPW roster rarely does US shows, if they do them at all.
