Yes - just found out that Shark is back - the 4 episodes that were finished post writer's strike to wrap season 2 up:

2.13, 2.14, 2.15 and 2.16 will be on TV (in the USA) on 29th April, 6th May, 13th May and finale on 20th May.

No news whether there will be a season 3 yet... But that will be announced after 21.5 but BEFORE 2.16 airs, so maybe we will have either a full wrap up or a cliff hanger to leave us dangling until it restarts.

I do hope they keep it going.
