I'm not waiting for an update. I bought the PX-5S because it does way more than my previous 88 key digital piano at half the price. It is very light, has excellent feel and action, and has fantastic piano, rhodes, wurlitzer, and clavinet sounds. It is the perfect keyboard for me and I got it for $899 CDN - I'm still blown away by that. It does so much more than I'd ever need.
