"Game of Thrones" is nearing its end with only two seasons away. While there are talks of prequels and story expansions, HBO recently clarified what the future holds for its biggest series to date.

Casey Bloys, programming president of HBO, recently spoke with Entertainment Weekly to set the expectation level of "got" fans surrounding the show's final season and possible spin-offs. Here's what we know, so far.

There won't be four spin-offs

It has been previously reported that there are four "Game of Thrones" prequels in the works, with four different writers assigned to each one.

According to Bloys, nothing has been set in stone and everything is in its initial planning stage. He hasn't even seen an outline from any of these four possible spin-offs.

Additionally, he clarified that it is highly unlikely that all four will be turned into a series.

The network's goal is to find a really good storyline and work from there.

George R.R. Martin will be involved, but David Benioff and Dan Weiss will not

"Game of Thrones" creators David Benioff and D.B. Weiss will not be a part of the show's spin-offs. The two have given up more than a decade of their lives developing "GoT" to be the massive success that it is now, and they now want to enjoy its offshoots as fans.

Fortunately for fans, "Game of Thrones" author George R.R. Martin will be at the helm of the spin-offs as a script consultant.

When will the prequel air?

HBO told fans not to think about the prequel this early. As mentioned, the story is still being developed and nothing has been confirmed yet. Also, the network wants to focus on the last two remaining seasons of "Game of Thrones." Season 7 is set to premiere this July [VIDEO], while Season 8 has not even begun production yet.

The creators are also planning a grand send-off for the now iconic show once it bids farewell.

However, HBO insisted that the prequel will be worthy of its predecessor. "Game of Thrones" has set the bar so high in terms of its cinematic story-telling, and the prequel will be just as epic.

'Game of Thrones' Season 8 might be delayed

Here's the sad news. The final season of "Game of Thrones" might not air by 2018 as originally planned. Fans may have to wait longer to see the series' conclusion, possibly until 2019. According to Bloys, the final season's script has not been worked out yet, and all filming logistics are dependent on it.

The silver lining to the delay is that fans can be assured that "Game of Thrones" will end with a bang. HBO promises that Season 8 will be more "monumental" than any other seasons.

HBO will be airing a six-season marathon beginning this Monday, June 5 in preparation for the highly-anticipated Season 7 premiere [VIDEO] on July 16.
