Following a recent meeting of the Bicycle Advisory Committee's Facilities sub-committee, DDOT has released a map of proposed bike lanes, bike boulevards, cycle-tracks and shared lanes for construction in 2013. The map is below. Here's a google map.

The map shows a pair of crossed bike boulevards in far NW at Jenifer and 41st Streets.

There are bike lanes or shared lanes proposed for Butternut, Blagden, Colorado, Piney Branch, Hamilton, Gallatin, Illinois, Rock Creek Church, Mt Pleasant, Adams Mill, Cathedral, Woodley, 14th, 4th, K and 10th in NW; on G, I, 2nd, 3rd, Brentwood Pkwy, and 8th in NE; New Jersey Ave in SE and Washington Ave and 4th in SW.

And of course, there are cycletracks on M St NW.

This is not a list of what WILL happen, and it's not uncommon for the list of what has been done in a year to be shorter than the proposed list at the beginning.
