30% is practically the standard. I don't think there's any evidence for Origin, but Valve and CDPR take 30% as per a tweet from Phil Fish.
Edit: Oh, and as further evidence for Steam, see THQ's receipt from CoH 2 sales -- if you scroll down to Attachment B, you'll see "Net Steam Sales" and "Revenue Share". The figure you arrive at after subtracting 30% from the former matches the latter virtually to the cent.
Many thanks
