New DSLR Series Coming in 2018? [CR1]

For the second time in the last couple of months, we're being told that a new DSLR series will be announced some time in 2018. Neither source could name the series, only that it appeared as a “new DSLR series” in a presentation.

If we're thinking out loud, I think these would be the obvious candidates.

• EOS Cinema DSLR
  • A cinema DSLR camera to replace the discontinued EOS-1D C. This has been talked about numerous times over the years.
• EOS-1D Xs
  • A high megapixel pro series body. Since the amalgamation of the 1D line back in 2009, we've always wondered if we'd get a camera like this to truly replace the EOS-1Ds Mark III. 
• EOS APS-C Cinema DSLR
  • A cheaper 4K cinema alternative that would “protect” the Cinema EOS lineup of cameras.

Hopefully this will bring a bit more information to the surface. For the moment, this is a [CR1] rumor, so please treat it as such.
