We have known about this camera for a while now and it is still believed that it is the Sony a7SIII, but it could also be the Sony a9II. I think Sony will answer the Panasonic S1H sooner rather than later with the Sony a7SIII, but I expect they will wait to announce the Sony a9II until Canon and Nikon launch their new sports cameras the Nikon D6 and Canon 1DX Mark III.
