Hard to believe the negativity here. The Rebel line has been very successful. It's become a very capable camera and a solid entry point into prosumer APS-C and full frame. How many of us started off on a Rebel? I used my 7 year old T2i until six months ago. Plenty of bloggers and Instagrammers, etc. are using Rebels very effectively. Also, the Rebel line has been used to test new tech, like the tilting screen, touch screen, DPAF, and even eye detect with the mirror up. Maybe they'll use it to test IBIS and BSI sensors. It's probably going to share a sensor with the 90D and successor to the M5/M50, offsetting dev costs. More important than raw tech for the casual user is probably advancements in UI and ease of use, maybe even AI assisted functions. And of course, it's designed to hit that $750 price target for those high volume Best Buy/Costco retail channels, while the 90D will probably come in closer to $1k.
The Rebel line is a lot of value and capability, with two decades of iterative improvement. It's going to sell. Chillax people. The middle finger that is the RP is what we should all still be upset about.
