I'm not feeling this rumor. Often these rumors of similar sizes get mixed up between the Pro and non-Pro models.A respected leaker is saying we will get BOTH a 10.2" iPad 7 non-Pro and an all new 10.5" iPad non-Pro, but at different times.

CoinX has an accurate track record, having previously tweeted the iPhone XS, iPhone XS Max, and iPhone XR names of the 2018 iPhones before anyone else, in addition to the 2018 iPad Pro being 5.9mm thick and a few minor details about other Apple products. It is unclear where the information is sourced from.

See ya in twelve days...
I think the rumor of the new 10.5 non-Pro is really about the new 10.5 Pro that will have the same design/style as the 2018 Pros that will replace the current 10.5 Pro and 2018 11" Pro. I suspect that this will be announced in Oct for the same price as the current 10.5 Pro.
If there is a 10.2 non-Pro iPad this year, I think it'll most likely be using the same chassis as the Air 1/2017/2018 but with slightly smaller bezels.
