The R6 has not had a major redesign since 2006 (thus the "6" in "R6"; the prior three years' tires were models RS303, RS304, and RS305...) At that time the R6 was - and some will argue "still are" - heads and shoulders above everything else so there was no need for any updates.
There are unconfirmed rumors that there have been relatively-minor compound "adjustments" in the intervening years, but the tires pretty much feel and drive like the same tires I won with on the NX2000 five years ago: very damn good.
Hoosiers are still the King of the Hill in DOT Radial "R compound" race tires. While there are, and have been, a lot of very good challengers, none have made a concise unseating of the Purple Crown.
