i expect nothing like psr1500 from roland. even exr was better build than psr. and now, e50-e60 having almost the same features as g70, i think they will have also good quality "box".
features like, e60 has obviously more than psr. keybed i expect to be better as well.
the rest, sounds, styles, etc is too personal taste to debate too intensively.

how much you'll use the power that the instrument offer is another story. some like better having everything ready out of box. some like tweaking and editing more.
the best always is to find the middle way.
