How long does everyone think it will be until Yamaha carries over the crossplane crankshaft technology, fly by wire technology or rider-selectable throttle control maps to program performance characteristics for riding conditions from the R1 over to snowmobiles? Or even a better question what do you think we will see next?
The crossplane crankshaft trades a second order vibration for uneven firing to help with traction on a bike-no advantage on a snowmobile.
Electronic throttles are a shitty idea on any vehicle because of delayed throttle response.
A switch to turn off engine braking reduction system would be a great technological idea.

I don't think we will see them. Like said before Electronic throttles would suck. IMO
Whole different ballgame as well. Temperature and terrain wise snowmobiles have to be tough they run in the cold weather and rough terrain for the most part. The R1 bike runs in warm weather and smooth highways so it may work on that bike does not mean it will work on a sled. I wish Yamaha would work on a clutch system and belt that would take the rpms. Then there would be no need to gear down the engine saving some weight.
The geared engine is a weight saving measure.
A direct drive engine will turn slower and be much larger and heavier as a result.

Sounds like we are going to need a switch to turn the engine braking on. But I agree rather then take away a great feature of the four stroke add a switch or program it into the speedo so those who want it can keep it. Those who don't can turn it off.

I love using the engine for breaks. And if you what to over come it you just stay on the gas a little.

If they were going to use any of it I'd think we'd have seen these those additions to the 2011 Apex

You missed the point totally. What's wrong with the engine turning 12000 to 14000 like the R1? Nothing the snowmobile clutching system can't handle it so instead of inventing something that can they geared the engine down so the clutching system already made can handle it adding more weight to the the engine.

Electronic throttles absolute garbage when it comes to the feel of operating the machine. Have one on my 5speed manual car, and it is absolutely terrible! Fly by wire will be removed and exchanged with cables on any future vehicle of mine.

At present the variable sheeve clutching systems we now use lose efficiency at an exponential rate at rpm's over 10000. It has been this way for years. Nobody else has been able to figure out a way to overcome this obstacle. I would guess there is some major engineering obstacle. The weight of the gear reduction system is not enough to be a deal maker or deal breaker. As far other new tech Pol has been working on antilock brakes. I would not be surprised if all sleds have them in a few years. For instant weight savings get rid of the parking brake system that Yami insists on adding on every sled. They might also use the deltabox frame as an oil resovoir making it possible to get rid of the oil tank. Little stuff ads up. The single ply tracks that other mfgrs are beginning to use also could be a big deal. Lighter rotating mass equals more power to the snow. I would also hate to see an electronic throttle on a sled. It works OK on tractors but that is about it.
