Mar 2012, Walter Briscoe remarked:
Neither Marlow nor Maidenhead is in the Oyster area.
I trust Crossrail will alter that for those who live so long.

Wonkypedia says it will, but without any citations to back it up.

Another reason why specifying Reading as the initial western terminus
might have been a "touch too far".

Oyster is already being extended to Shenfield as part of the new AGA
franchise. It's not on the map yet (stops at Harold Wood).
