43rumors.com says that the Panasonic G9 II will be announced very soon, but made no mention of the S1H II or the S1 II, which are expected to be announced in the fall to early spring. No specs were provided, nor did they indicate pricing, but we do not expect much of a price increase over the mark 1.
If true, the summer should be anything but boring with two Sony cameras expected including the a6700 and the A7C II along with the Panasonic Lumix G9 II.
Perhaps Canon might have something too?
