Michael Dresser mentions this:

The proposal being batted around in Prince George’s would take the Green Line as far north as Route 32 near Savage before it would curve east toward Fort Meade and Odenton. That would make it a lot easier to get to Washington via Metro without getting mixed up in traffic jams.

He also links to the Greater Greater Washington post on the subject. Dresser proposes that the MTA in MD get together with the WMATA in making the two systems more connected if this happens. He mentions the possibility of the light rail connecting to Metro somewhere as well as the B30 bus from BWI making trips to the new terminus of the green line (it now goes to Greenbelt.)

Another intriguing proposal Dresser mentions is allowing for off-hours or weekend connections for MARC’s Camden Line in the Savage or Laurel area.
