Didn't Apple learn from the 24K "celebratory" watch that was out of the price range of your average consumer? This Ceramic one and Titanium may solve that, but if the price is too high for people, then forget it.
The Series 3 Apple Watch Edition in Ceramic was $1299 for the 38mm and $1349 for the 42mm.
If there had been a Series 4 Apple Watch Edition, I would expect it to have been $1399 in 40mm and $1449 for 44mm (in line with the price increase on the Aluminum and Stainless Steel models).
As for Titanium, I could see it having gone for $200 more than Stainless Steel, which would have put it at $899 and $949 as a Series 4.
