I wondered, after the R5 overheating issues, if the R1 was not in the works yet because of thermal issues. I think these typically get a dual Digic set up, and if one of those bad boys is throwing lots of heat imagine 2.... That's not to say they wouldn't just do a single next gen Digic, but it was just my thought that the processing required for an R1 series could be a limiting issue at the moment.
The larger body with built in grip could give them some opportunities though for heat dissipation ideas.
And no, I'm not trying to sound the alarm that this thing is going to melt down or what not.
I'm just really excited to see what this can do. I imagine its hard to top the R5, but perhaps they have something up their sleeve. Top of the line EVF, faster mechanical shutter, smarter focus tracking AI....who knows. I imagine they'll forego any 8k video. Maybe land this on a 24MP sensor to differentiate from the R6, but still not go overboard for what most users need. Maybe instead of memory cards it will have a slot for one of those m type SSDs (crazy idea I know).
I'll never own one, but I'm still excited to see what it can do.
