The way I read the info it would mean that they put in the same keybed that is in the G-1000 arrangers, which a lot of people liked and some didn't like because it was too heavy. In other words, it is somewhere between a "synth" or "organ" feel and a "piano weighted" feel; this is sometimes called "semi-weighted". Both the Tyros and the Pa1X are "tongue in cheek" weighted, ie, they have small metal weights affixed underneath the white keys to give them a better feel.
