Since the Nikon Z mirrorless system announcement, everyone is waiting to see how Sony will respond. There have not been any reliable rumors on what's coming next from Sony (except the regular guesses: a7s III, a6700 cameras or maybe new 200-600mm and 24mm f/1.4 GM lenses). Today they announced the world's toughest and fastest SD card and they also have a countdown timer on their website for an August 30th announcement, but that's about it.
Btw, the big Sony deals are still live. More on those new memory cards:
