Today, I went Kayes music and saw the new Korg PA 800 and overall I think the keyboard was awesome, but since I own Yamaha Tyros 2 I just want to compare the two keyboards. George at Kayes Music he was very helpful in comparing them. Since I use lots of custom styles and sounds, the new PA 800 will be lots of work. As far as the new keyboard goes, it is very user-friendly with realistic sound in live performance,but at the end I can say Tyros 2 works better for me because I'm a Yamaha person!!
P.S. Thanks to George Kaye for his time and effort.
