how long until the old school saws will be replaced by greener ones?

there are already several battery powered saws on the market.

Thats true but they are designed for small jobs such as pruning or limbing. As far as I know no one makes a battery powered saw for heavy work. I think 4-stroke technology is something to watch. I known Dolmar has a good working prototype now. Not much on the rpm side but very good on torque. If it is as good as their other 4 stroke trimmers it could a viable option. A little heavy, but Iam sure they will work on that
My local dealer is due to go and see one of Stihl's new battery saws next week I think. It will be running off the batterys as used by the new hedge trimmer and is very much an battery 017 so he tells me.
If you search back there is an old thread about the first modern single man 4 stroke saw which was being sold by Makita.
Stihl MSA 160 C-BQ
I think it is already out in Germany.

4 stroke saws and trimmers aren't the future, Stratofied charged two strokes are.
Look at Husqvarna and Stihl the two big dogs on the block, all the newest saws, trimmers, and blowers are Stratotfied charged motors. If 4 stroke was the future don't you think the new Stihl trimmers would be 4 Mix engines, but they haven't had a new 4 Mix product in 5 years.
I wonder who Stihl is going to market that saw to?
It looks like it'd have the same life expectancy of any home owner saw...a few years.
The reason has nothing to do with the saw itself...that'll probably work fine. But the battery. A typical Li-ion battery looses capacity over time. In 5 years you'll be at half of what you started with or less. Which might not be that big of a deal if you just need to take off a few branches, but still seems rather complex and expensive for what it is.
A real electric chainsaw will come out when we have electric cars that can go 400+ miles on a charge...ie when we have something that can hold a power density about 10x what we have now.
A super capacitor, better batteries, don't know...but until then I think gas is here to stay.
You may well be right about that! But remember that with 4-mix you still have to mix fuel. And they are way heavier. The Dolmar 4 stroke is just that, a true 4-stroke! I do prefer the strato though. More like a conventional saw,and I believe they may outlast the old school stuff due to running a little cooler temps because of the air injected into the cylinder.
