1) We've seen this before. None of these posters have actually ridden it.
Even the AMS Dallas sales guy said the model he had for viewing was pre-production and not ridden.
Perhaps it will have an up-down QS, but one would think that Ducati would confirm such a feature which they have not yet done.
Until official confirmation, I remain cautiously optimistic.
2) About retro-portability
If it's anything like the new Monster's QS, then it's not portable as the electronics are completely different. I've looked into this first hand. Again, until official confirmation...
In the interim, the after-market products are your only solutions. On that note, RapidBike does make a new up/down QS accessory reasonably priced at around $400 for those that own their fuel controller.
