As far as I know there have been two quite similar RGT6EXFXs since 2006, originally both Japan models: the RGT6EXFX with basswood wings (since it's a neck-thru) and the RGT6EXFX2 with mahogany wings. For 2009 Ibanez dropped the basswood one and probably simply renamed the EXFX2 to RGT6EXFX (that is if it's actually has a mahogany body).
Bottom line: the 2008 model sold in the US had basswood wings, the 2009 has mahogany wings (according to Ibanez themselves). Since that is pretty confusing, shops probably mess it up.
