I only looked at the new YPG625 for a few minutes at NAMM. The display looked the same to me as the DGX505. The button layout is different though. I do think it has the same 1 user style load functin but I'm not sure. The YPG625 has the GHS weighted piano keys and the YPG525 has the semi-weighted keys of the DGX505.
