BTW, just to address the size and weight comment...

Roland made a VERY capable 76 with quite a nice action, AND built-in speakers for only about four pounds more than an S910, the E60.

If Roland can do it, SURELY Yamaha would have no problem, and those happily lugging an S910 around (or the even heavier Tyros4) would have no problem. Few lug their arrangers around in cars, and gigging pros ARE the exception, rather than the rule. Moving an E60 around the house is no more burdensome than the T4 (less, actually). Time after time, excuse after excuse is so easily proven wrong, it makes you wonder WHAT you are thinking, offering up such flimsy excuses..?

If Yamaha had only ONE division that made and sold ALL keyboards with arranger capabilities, whether in piano cases, lightweight cases, 88, 76 and 61 sizes, I GUARANTEE that there would be a TOTL 76 in their line-up...
