The Television Critics Association panels are currently underway, and today was HBO’s turn to drop some news nuggets.  Chief among the cable network’s announcements is an official premiere date for the upcoming fourth season of Game of Thrones, which will kick off on Sunday, April 6th at 9pm.  The insanely popular fantasy series will be joined on Sunday nights by the third season of Veep and the debut of Mike Judge’s (Beavis and Butthead, King of the Hill) new live-action comedy series Silicon Valley, both of which will also premiere on April 6th.  Additionally, Ryan Murphy's feature film The Normal Heart will premiere in May, and Damon Lindelof's new series The Leftovers will debut this summer.

The fourth season of Game of Thrones will largely cover the second half of George R.R. Martin’s third book in his A Song of Ice and Fire series, A Storm of Swords.  We'll see our first trailer for season four this Sunday, in front of the premiere of True Detective.  Good luck watching the opening credits without this song stuck in your head.  Hit the jump for news on the final season of Boardwalk Empire.

Additionally, HBO announced today that this fall’s fifth season of Boardwalk Empire will act as the show’s last.  Steve recently spoke with creator Terence Winter about his plans for the end of the period series, and he revealed that he and his writers would be determining an end-date when they reconvened to start planning season five.  It appears that they settled on one final string of 13 episodes to conclude the exploits of Nucky Thompson, who is played by Steve Buscemi.  No official premiere date for season five has been announced, but it will likely be sometime in September.  Look for more from the TCA's soon here on Collider.
