There doesn't seem to be a tidy cut-off date where there's a consensus of what's no longer vintage. They'll probably continue it until it no longer sells. As far as when that will be, who knows. Personally, I think they are hastening it by trotting out the old designs for non-Heritage stuff, like we saw in Lineage and Archives. Plus at some point they'll be rolling into the era where the original cards aren't as hard to find so the 'historicness' of it will be greatly reduced.
