And would be even MORE profitable, were they to make a DGX or YPG that had the latest OS, styles and sounds from the PSR line.

Here's a simple (even for you!) test you could do. Talk to a YPG or DGX owner. Play him (or her) something off your S910. Ask them if they'd like a DGX that sounded that good...

OF COURSE they are going to tell you 'No!'... They play a 76 specifically so that they can have an inferior product to a PSR, don't they..?
