"How long will Samsung support the S8 with updates"
Well, if I might draw your attention to the charging cradle for my Gear 2 Neo:
11 months after I got it, I managed to lose the charging cradle. Not to worry, there's a Samsung store just down the road from the office.
"I'd like a charging cradle for this please"
The salesdroid looked at my Neo, pointed to the S2 display in the window and sneered "Oh, we don't do *those* anymore. Have you tried eBay?"
So I imagine the S8 will be supported right up to the moment you walk out of the shop with it.
