New Remington ammo question

So I've been following the recommendations more closely as of recently, phasing out the lightweight Hornady stuff in favor of heavier Speer Gold Dot ammo for the 9mm and .38 Special ammunition. It's easier to find than some of the other recommendations, especially the Remington Golden Saber ammunition which can't be found anywhere. But recently I found something called Remington Ultimate Defense ammunition in various calibers, and it looks exactly like the Golden Saber ammunition. Is the UD the new generation of the GS ammo by Remington?
