Wikipedia says "as of 2009" but I don't know if that was the first release that year or just sometime that year.

Pity. Means I can only really buy them in R4 from now on.
Not that I've bought one in 5 years...
The Region 2 discs released up to 2009 have also been dual coded with Region 4, so the two have been identical. This practice ceased for new releases in 2009.
