Game Of Thrones
Fans are eagerly awaiting new details from the "Game of Thrones" panel at this week's San Diego Comic-Con. HBO

Watching the "Game of Thrones" Season 5 finale was a gut-wrenching journey. There was the thrill of all the big hits that were happening during "Mother's Mercy," the shock and disbelief following several major deaths, denial that their fate was sealed, and now the look ahead to "Game of Thrones" Season 6. The HBO series has put out casting calls and has begun scouting locations, which means production is in full swing.

Based on past season premieres, the best guess for the "Game of Thrones" Season 6 premiere date is April 2016. The "Game of Thrones" Season 5 premiere, "The Wars to Come" aired April 12 and the previous season aired on April 6, 2014. "Game of Thrones" Season 3 aired March 31, 2013, "Game of Thrones" Season 2 premiered April 1, 2012, and the first season hit HBO way back in April 17, 2011.

Using deductive reasoning skills that would make Sherlock Holmes proud, there are two very feasible "Game of Thrones" Season 6 premiere-date candidates. For HBO, earlier is usually better and most seasons have premiered in the first half of April. April 3 feels a bit early, which means April 10 or April 17 may be the date that fans will have circled on their calendar.

There will be no official confirmation on a "Game of Thrones" Season 6 premiere date until December or January -- based on previous HBO announcements -- but fans won't have to worry about a drought when it comes to "A Song of Ice and Fire" news. There will be casting news and speculation and last year included a big Dorne reveal at Comic-Con.

While there may not be a whole kingdom that will debut next season, there are several characters that could get introduced. Based on previous news, many expect Euron Greyjoy -- Theon and Yara's eldest uncle -- will be a major player in "Game of Thrones" Season 6. Bran will also return next season and it would be fun to see Isaac Hempstead-Wright make a public appearance to get fans excited.

For now, fans can keep speculating about Jon Snow's fate. Series creator Dan Weiss and actor Kit Harington are pretty adamant that Jon is very much dead at the end of the "Game of Thrones" Season 5 finale, but sometimes death isn't so permanent in Westeros.
