Week old news but anyhow, the last two ME3 DLCs have been announced.
Citadel for SP

All good things must come to an end, and that includes the Commander Shepard trilogy. However, just because it is coming to an end, that doesn't mean we can't go out with a bang. Introducing the final Mass Effect 3 single-player DLC: Citadel!

When a sinister conspiracy targets Commander Shepard, you and your team must uncover the truth, through battles and intrigue that range from the glamour of the Citadel’s Wards to the top-secret Council Archives. Uncover the truth and fight alongside your squad – as well as the cast from the original Mass Effect and Mass Effect 2.

When the adventure is over, reconnect with your favorite characters from the Mass Effect Trilogy, try your luck at the Citadel’s Silver Coast Casino, blow off steam in the Armax Combat Arena, or explore and furnish Shepard’s own living quarters on the Citadel. With unique content and cinematics featuring your friends and romance interests in the Mass Effect trilogy, Mass Effect 3: Citadel offers one final chance to see the characters you have known for years and rekindle romances.

Mass Effect 3: Citadel will release worldwide on March 5th on Xbox 360, PC and PS3 (on March 6th on PS3 in Europe).
Thus comes to an end the saga of Shepard and his crew. Three games, hundreds of hours and many many thrilling, bitter and happy moments.
And despite the things that were done wrong, the games also did many things right and would always have a place on my shelf.
