I asked local Stihl rep about this today and he doesn't know when they are coming to Canada. If they come here first I might do a port job on a new one.

Especially being that it’s only been out for a couple years, seems weird to kill it off this earlyGreat, now I'm going to have to stock up on spare parts for the 400 I have.why on earth would stihl kill off an already great saw?
I don’t think we’ll see another injection chainsaw from Stihl. If they did, direct injection would be cool.
Pick your favourite reason.Great, now I'm going to have to stock up on spare parts for the 400 I have.
1) Despite what you read on the internet, it's been an unreliable saw and is costing to much in warranty claims.
2) The magnesium piston is to costly and a redesign will reduce the COGs on this saw.
3) The current 400 is to close in displacement and weight to the 462 and to big a gap to the 261 (once they get rid of the 362).
I think option 3 is the reason.

good thing my anniversary is tomorrow, now when the wife asks what I got her, I'll tell her I preordered 2 of these lol
option 3 would seem the most logical, but still doesn't make sense. No reason to launch the 400 if they wanted to update the 362 again.
Stihl will never give the truth.
I’m betting it’s the cost of producing the magnesium piston.
We usually hear of issues on these forums before most dealers are even privy to them. Piston scoring is the only issue that comes to mind on the 400, but I don’t believe it happens to that model more often than other models.

I don't know that casting magnesium is much, if any more expensive than casting aluminum. The metal itself might be slightly more expensive given it's probably a magnesium aluminum alloy.
Hopefully the 400c cylinder will fit on the new version.
Stihl may have a liability concern to do with a failure of the ceramic coating over the magnesium piston. Magnesium is highly flammable, and even explosive… if failure occurred, obviously you’d have one hell 
of a hot saw in your hands.

Suddenly I want one of the early versions.

Pure magnesium which i'm sure they didn't use, depending on the alloy some are not flammable at all even if you hold a torch to it.Stihl may have a liability concern to do with a failure of the ceramic coating over the magnesium piston.

Typical Stihl. Change something that works great and people like, like this saw and 25-2 trimmer heads
Leave things that give problems like bg56, bg86 crank bearings cages breaking up and ts420 mufflers coming off.

And most pro crankcase are a magnesium alloy too.
The piston also likely an alloy, just like "aluminum" pistons.And most pro crankcase are a magnesium alloy too.
I've been wanting an MS400 to fill the gap between my 550xp mk1 and my 7900.
I've been holding out against the CAD. Will be good to hear the pros and cons between the current and new model. I think I'm leaning towards the slight extra power and assumed torque of the current model.
What could tip me over to the new model would be feel, flickability and a smaller forum factor.
Hope we hear all about that soon.

Looking at the pics, I'm pretty sure the rear handle moulding is new which I read was a weakness on the 362 and 400.
I doubt the new model will handle much if any different, slightly less wight and hp. Haven't heard of any tank handle issues unless someone was running an abnormally long bar for whatever reason on the current model.
