Meanwhile, back at the ranch...
Yamaha spiffed up the MODX synthesizer adding more expansion memory, more FM-X polyphony, new pitch/mod wheels, and ---------- not much else other than a plus sign to the name. This brings MODX+ tone generation up to the Montage spec. MODX+ Seamless Sound Switching remains limited to 4-part Performances (Montage: 8-part SSS).
Perhaps -- as Derek suggested in another thread -- Genos will get a spiff and a plus sign, too. Kind of deflating to all those grand plans! 
Back to the usual bickering about plastic, click-bait fakes, sustain pedaling, version 2, ya-da, ya-da. 
Peace -- pj
Great! I was just getting ready to post about a North Korean video I saw that previewed the Genos-5, and it included enhanced sustain as well as the ability to simulate Leslie speaker speed-up and slow-down using actual samples! If it's on the Internet, it's gotta be true, right

. Okay -- Just joking -- If that wasn't obvious!
But that MODX+ ... Yeah, that caught me by surprise, as I had no idea that Yamaha was coming out with a new synth at this time until I read about it here maybe a day or two before it was introduced. But, as has been said, it seems just like a minor upgrade to the previous MODX, and that is implied even in the model name, where they just put a "plus" sign after the original name. Kind of like when Yamaha came out with the PSR-S775 and S975, which were just minor upgrades to the S770 and S970.
It would be cool if Yamaha came out with a new small synth -- something like my Roland Gaia SH-01, the Korg OPSix (which may have been discontinued), and Classics like the ARP Odyssey and MiniMoog. Something that is maybe about 3 octaves -- but with FULL SIZED KEYS -- and that is small, relatively light, and can be used in conjunction with other keyboards to enhance playing/performance options. They have the reface series, but I just do not like mini-keys. I don't see guitar manufacturers selling "mini-guitars" at music shops (unless it's a ukulele), so I don't see why keyboard manufacturers insist on telling keyboard players that they need to scrunch their fingers together to play an instrument.
Also, a re-issue of the CS-80 would probably sell like hotcakes -- at a good price -- seeing as to how I've now seen asking prices beyond $60,000 US for the original!
