The only new piano that Yamaha came up with this year (2012) in their Arius series was an attractive polished ebony cabinet finish of their YDP161 which they call 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 very nice piano tone and fairly nice and solid piano key action (GH).
However, the YDPC71 is somewhat basic in most every other way based on its higher price when it comes to its limited control panel where all controls on the left side of the piano which is somewhat inconvenient in my opinion, limited instrument tones & educational technology, and no USB output or USB flashdrive input unlike other digital pianos in this price range including the new Yamaha models which have some of these upgraded features and functions. In other words, for $1799, other than getting it in the polished ebony finish (which I admit costs more money to produce and is very 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 would be a much better choice as a musical instrument goes in my opinion, and for not much more money in its basic brown rosewood cabinet (polished ebony is more money).
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 in this higher price range (nearer $2000), I would choose the Kawai CE220 or Casio PX850.
With regard to the Yamaha Arius model YDPC71CE, the up side to this instrument at this price point is that if you are a "minimalist" kind of person who wants 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.
