Considering that single travel tickets cost 3€ at the moment, and yearly ones 730€, that would be a godsend. One can also hope that one day they'll allow traveling on a single ticket for the full two hours, not just for one journey. However, it's unlikely the BVG will ever budge on pricing.

Earlier this year, there were rumors of a cheaper "Homeoffice-Ticket" which would only be valid on certain days, and in the end nothing came out of it either.
