I also have seen leftover 2014s at wildly varying prices. I have seen just in the last two weeks in Amazon ads the same two 2014 LP Root Beer Min-e tune LPs listed at $2699, $1599 and now at $2999.
Oddly it has become an 'arab market' for Gibson Les Pauls. Prices are all over the place. You could get a bargain or pay way too much, its become essential to scour the internet. Although I would like to support my local dealer, he was consistently expensive on the 2015 LP's, literally hundreds of pounds dearer than many other online Gibson dealers. Only a couple of weeks ago an ad appeared from one of the main UK Gibson dealers showing the full range of 2016 Les Pauls, including the HP's, at massive discounts. No sooner had it appeared than it disappeared (within two days). Now you wonder if that was an ad prepared for the clearance of 2016's after the influx of 2017 stock, and released prematurely?? The many folks who saw it probably think so and will hold back on that 2016 LP purchase........
