I already admitted I was wrong, as I’ve done regarding other matters. But, since you seem to need it personally, I’ll reiterate: I predicted there would be no APS-C EOS R body, and I was wrong.
I maintain the R7 is not a true successor to the 7DII. The analogy of the 1D X holds – 1Ds, 11 MP; 1DsII, 16 MP, 1DsIII, 21 MP...see the pattern? 1D X, 18 MP. Not a true successor to the 1DsIII. Canon says it is, because they wanted 1DsIII owners to buy the 1D X. There wasn't a 1DsIV. There are plenty of people on this forum predicting that the R1 will be the spiritual successor – a high MP 1-series body. I doubt it, but time will tell. Similar with the R7. I doubt there will be an APS-C EOS R line sitting 'above' the R7.
As I've said many (many!) times, Canon knows the market better than anyone on this forum. That definitely includes me. I'm truly surprised there apparently is no vertical grip for the R7. But Canon knows how many grips they sold for the 90D and 7DII, and they apparently chose not to develop a grip.
