I keep poking around on here waiting to hear some rumors and maybe even sneak in some spy shots. Anyone have something to share?

I know nothing but would be shocked if they don't go wireless.

What makes you think that Shimano is going to do anything other than their typical 4 year update cycle for Dura Ace?
2004 - 7800
2008 - 7900
2012 - 9000
2016 - 9100
2020 -

Shimano cannot make derailleurs with batteries attached without infringing on SRAM's patents. In order to go fully wireless, they must be able to do that. The alternative is running wires to frame-mounted batteries, and at that point you may as well run one centrally located battery like Di2 and FSA WE do now. Another solution would be Shimano's dynamo pulley wheel + capacitors in the rear...not sure how they would handle the front.
In the meantime Shimano will continue to claim they aren't interested. They're attempts to get around the patents say otherwise.

To better match the staggered 3 year update cycles the bike manufacturers are settling on, and because sales volume is decreasing, so they need fresher product more often.

With amount of stock and demand of new XTR. I doubt their factory is ready yet. They might end up announcing product that they can not produce to meet demand for another year while at the same time people don't want their old product anymore. Doesn't sound like a good plan for me.

What kind of patents? A battery/anchor type Sram or any other type of battery/anchorage???
It will not be also that being the Di2 a more complex system, for other types of bike apart road and MTB, Shimano does not trust 100%, in a completely wireless system??

In the patents for the physical designs of the eTap RD and FD, the description includes directly attaching batteries to the structural members.

I'm geting a new tandem frame and I've opted for the Di2 option, including a custom two-piece eccentric that allows a wire to pass through captain's BB. Running a Di2 wire on the tandem is more complicated. Wireless would be nice on a tandem but there are too many hurdles to overcome to adopt AXS on a tandem. I'm not worried about any new product announcements by Shimano. It's gonna be a while before the new wares hit the shelves. In the meantime I want to enjoy what's available today.

Yup they have to get XTR back on track.... i think it's the same factory for their top tier parts. Bad enough the XTR crank is not the announced one and Sylence is on the shelf for another generation.

Becaue waiting two years to catch up to the other company's 12-speed gruppos is not in their economic self-interest.
