I'm not trying to convince you to go to a 76 Ian... Yamaha don't make one... not gonna happen!

BUT... if the opportunity ever DID arise, you might be able to judge how well they would work for you without the bad taste that changing to another brand altogether (or putting up with a lousy DGX or NP-80v) would put in your mouth. After all, if you never had HAD the opportunity to find out if it might work for you better than the current situation, you can't really say it wouldn't be your choice.

Sure, what you have NOW works perfectly for how you play, NOW... But a large amount of HOW you play depends on the capabilities of WHAT you play. And all of us, no matter how old we get, should like to consider that we can grow, musically. If more capability can be added to your arranger, at the cost of little gain in weight and size, and ZERO loss in sound and operational ease, it might be harder to make that decision to eschew it if you actually DID have the choice.

It's all well and good to theorize about what we MIGHT do under a set of theoretical circumstances, but if life has taught me anything, it's that we never REALLY know what we are going to do until the circumstances actually arrive!

Never say never!
