The only thing that Yamaha came up with is a new polished ebony cabinet finish of their YDP161 for the YDP-C71PE at $1799 internet price (upper left pic). The YDPC71 is otherwise the identical digital piano to the Arius YDP161 ($1499 internet price) which has a nice piano tone and fairly nice and solid upright piano key action (GH). However, this model is somewhat basic in most every other way when it comes to many things including its control panel which is minimal, limited instrument tones & educational technology, and no USB output to iPad or computer or USB flashdrive input unlike other digital pianos in this price range which do have some of these upgraded features and functions. In other words, for $1799, other than getting it in the attractive polished ebony finish (which I admit costs more money to produce and is nice to look at), there are better new digital piano choices out there that are more advanced including piano sound & key action realism. In fact going up just a bit to the Yamaha Clavinova CLP430 in the standard cabinet finish would be a much better choice as a musical instrument goes in my opinion, and for not much more money.
With regard to the Yamaha Arius model YDPC71, the up side to this instrument at this price is if you want to keep it very simple with minimal functions, and you really want that polished ebony high gloss look in a digital piano (and you don't mind spending the $1799 to get it), then this piano may be just perfect for you.
At the end of the day it really doesn't matter which piano you get because you'll be able to make great music and have a nice piano that should last you many years. But for my money and considering I would want the biggest bang for the buck, I would choose the new Casio Privia PX850 any day over the Yamaha YDPC71 and save $700 in the process.
