Like so many others here, I had very high hopes and excitement about eventually purchasing a Pa3x back in Dec, and was then planning to hold off on a TOTL keyboard upgrade until Namm, when more solid info would be known what it would actually include, especially considering the speculation floating about that the Pa3x woud be a major upgrade from thePa2x. I only opted to upgrade to Tyros 4 sooner because I received an early Christmas check from Santa and couldn't keep it in my pocket, and also realizing back then that the Pa3x probably wouldn't be available in stores till April-May 2011, giving me 5-6 months to test drive the Tyros 4. Fast forward to today, and I'm happy to report that I'm happier with my Tyros 4 than I ever expected, and that my interest now in purchasing a Pa3x, after talking and dicussing about it with friends that saw and played it live at Namm, watching the original uncompresses HD videos they shot, and now watching this latest video here from Italy has me very let down of any hopes that The Pa3x will be any more than a minor upgrade from the Pa2x, similar to what Tyros 3 was compared to Tyros 2, and which was the reason I passed on a Tyros 3, and waited to purchase Tyros 4 instead.
At this point, short of a miracle, I doubt The Pa3x will have much to offer for Pa2x owners other than the Chord Sequencer and a few 'catch up' to Yamaha features such as fill to self. The bigger interest will come from people who don't already own a Korg arranger, and that still 'might' include me.
