There WAS a RG521 a few years ago, with the Wizard neck and no binding. It was a spot model, released at Summer NAMM. It wasn't publicized much, but still sold out due to limited numbers. Like many spot models, it was used to gauge if the market would support such a guitar. A year or so later, the RG421 made it's appearance. The neck was made thicker to appeal more to "rhythm" style of player and the binding was added to make a visual difference between the 521 and the 421.
If I were a betting man, I'd wager that the 421 is being discontinued in lieu of a cheaper model. Let's look at history. The RG7621 was discontinued and became the RG7421, which became the RG7321. I would not be suprised to see a RG321. I guess we'll see in January.
