Canon realizes the most of the sales loss bulk this year was the low-end Rebel models. Their financial report emphasises on that fact. So I believe the rumors of a new T7i and now a new Kit lens are aimed at shaking up the low-end models sales, make users of current post-550D want to upgrade.
They just really made the t6s and t6i and they wouldn't upgrade them so fast for no reason, so it's consistent with what's happening...
I am guessing a new rebel with some exciting new features (yet still not embarking on the 80D territory) is coming, along with an exciting kit lens upgrade. Why upgrade the current STM 18-55mm, it's freaking good and new!
We can suspect:
1- Same Lens with new coatings, slightly refined optical formula, refined look, IS, etc and call it IS STM II
2- Nano USM motor, same optical formula, PZ compatibility. (My guess)
3- Collapsible design of the current STM.
4- No real change. Just a cosmetic refine.
The camera, I am guessing one model with the upper LCD and front dial (t6s design), 24mp DPAF sensor, 1080p 60p at a lower price than usual. An 800D. This would give it a push over the current offerings and be a hit for new comers and 550D upgrades.
Of course this news and rumors are not exciting to someone who needs AFMicroAdju, 7-8 fps, Magnesium alloy, big dials, more buttons, larger buffer, dual slots, Fullframe, 4K, etc, but it IS exciting to me to see what Canon makes in their entry level model.
The T6s is a brilliant camera to hold BTW. Absolutely lovely body in design and ergonomics. Has all the buttons and dials and upper LCD and touch LCD that swivels, rugged, not too big or too small, just really, really refined design. The front dial is a bit small but that's it. It's a brilliant body really. Like it way more than the 80D/7D body. One with the 5D sensor at 1600$ would be so cool wouldn't it?! Plastic, 3fps, 19 AF points, we don't care. And pair it with the 24-105mm STM IS in kits.
