Doesn't mean anything. They've already said wp8 phones will get wp9 update.
So it just mans if you do t update you won't get support.
We'll be on 8.8 by then, pointless MS supporting the people who refuse to upgrade their OS.
7.5/7.8 users were on the old kernel, 8 has the NT kernel in it so I should expect upgrades for the foreseeable future.
Giving 2 years support for a mobile OS is pretty good, its about as much as you get on an iPhone
OK, that's my fears allayed

I thought as much but I'd not had the time to read any further into it.
