If I were in the market for a new guitar and had the requisite funds on hand, I would buy one now rather than wait for a later model. Wood availability being what it is, the odds are that that quality of wood available today is likely to be superior to that available in the future. Furthermore, as wood supplies dwindle, their cost goes up and guitar prices either go up or are held in check by switching to less expensive types of wood, which may not be as desirable.
