"...I believe anyone who hears this keyboard and questions if it is better than a Tyros 3 can not hear what everyone else can hear. It simply blows the Tyros 3 away."

I would question the validity of this statement. Everything I have heard on the T4 thus far I wouldn't say "blows" the T3 away at all. They still do sound similar with the exception of some additional new sounds on the T4 as well as installing some "gloss" over what was already exceptional in the first place.

No doubt about it, the T4 sounds like fantastic board but certainly the T3 wouldn't sound out of place next to it.
