It’s been a big week for geek TV news, which we round up here.

HBO has released a new Game of Thrones poster promoting the final season, featuring an arrangement of apparently dead characters from the show such as those left by White Walkers in the past.

The ratings are in from the season finale of The Walking Dead, and although they’re up from other episodes in the season, the episode had the lowest ratings of any season finale since the beginning of the series, according to The Hollywood Reporter.  Around 5.02 million viewers watched the finale; the previous low was just under 6 million, for the season finale of Season 1.  While the season ratings were down a whopping 37% in viewers from the previous season, the series remains the most popular show on cable, with more than twice the viewers of the second most popular show, VH1’s Love & Hip Hop Atlanta.

Netflix’s Umbrella Academy has been renewed for a 10-episode second season, Dark Horse Comics announced.  Steve Blackman will continue as showrunner, and Ellen Page, Tom Hopper, David Castañeda, Emmy Raver-Lampman, Robert Sheehan, Aidan Gallagher, and Justin Min will return to the cast.  The first season has been driving graphic novel sales to an unprecedented extent (see "February 2019 BookScan – Top 20 Adult Graphic Novels").

Warner Bros. has signed a big new deal with Roberto Aguirre-Sacasa, who’s Chief Creative Officer of Archie and showrunner for WBTV series Riverdale and The Chilling Adventures of Sabrina.  He’s also co-developer and writer on Katy Keene, a Riverdale spinoff (see "Katy Keene on the CW").  Aguirre-Sacasa will continue his work on all three shows under the new deal. His new deal is for five years and high eight figures, according to the report.
