They usually offers 1-3 new models per line; a couple of RG's, maybe a new S, maybe a few Roadcores or Artists. I usually don't expect more than 6 guitars or so total. And usually they're variants of existing models. Maybe a new color or a maple board option on an identical model that has a rosewood board.
Hmmmm. A maple board on an RG652FX. How tasty would that be?
