The release Yamaha sent out stated that the CL was discontinued "immediately" and the QL would continue to sell until current stock was depleted.
I do not expect there to be any discounts. Demand for remaining QLs will likely go UP now that it is known that their days are numbered. QL1s in particular fill a specific niche in corporate/convention audio that no there console so neatly fills. And that niche doesn't need and will never need the additional capabilities than the QL1 offers. Given that Yamahas last forever, I expect to still be mixing small shows on QL1s for the remainder of my career.
I'll add that "discontinued with immediate effect" usually means either "we can't get the parts any more" or "there are lawyers involved". And given that the QL is continuing until stock is deleted, it's almost certainly the former. So I wouldn't hold my breath for discounts.
