Also ..the G70 harmonizer is much better than the Korg..It analyzes better and has more capabilities...
At 2 grand..people should jump at a used G70.. 
Most folks..worry about the OS..and think the G70 is too much board...hence the panic selling...
Players that know better..won't part with a G70..as Diki says..it is the best possible live play keyboard on the market....I'll admit I did not try one and went soley on the "market" sentiment. Early this year I went looking for a G70 and saw them not selling on Ebay for as low as $1800 used and $2000 refurbished. While used T2s were selling for over $2500 and the PA2x was perpetually back ordered. I waited teo months for mine. So I knew the Yamaha but liked the ton of features (on paper) of the Korg. The PA50 manual is 4x thicker than the T3!!!!! LOL
I was happy with the Korg and felt it was and is a great unit especially for live OMB use. I would buy a PA800 in a fire sale in a minute. But the PA2x had far too many features I found out I would never use.XLR Mike inputs, harmonizer,dual sequencers/Mp3 players. I was disappointed in the button and slider build quality using the same buttons and sliders for the past 10 years, When the T3 became more than a rumor I decided to sell the PA2x just in case the T3 changed the game for all Arrangers. Which I don't believe it did, However for my needs its perfect and the 3rd party support second to none as well as some of the voices.
I believe its far more than a simple T2 upgrade in many areas not the least being the capability to add voice packs and the new EFX engine. I do not like the IDE drive and (dated DIMM memory) use and may have to stock a few while I can get them.
Plus you have to remember I paid less than a new PA800 for my T3 which makes it all the sweeter.
