An announcement as to the release of the next installment of the "Assassin's Creed" franchise will be made very soon, according to "Assassin's Creed 4: Black Flag" lead writer Darby McDevitt.

In an interview with Edge, the lead writer discussed the future of the AC franchise, revealing an end to the series isn't exactly set in stone.

"We stayed on course maybe 75 or 80 per cent of the time," McDevitt told Edge. "The end of the Desmond trilogy changed slightly but it was always intended to end that way. And then about two years ago we planned for another story - there's been a bit of confusion in that [Black Flag game director Ashraf Ismail] once said that Assassin's Creed has an ending - that's not exactly true."

"This storyline has an ending, but because all of history is open to us we see the universe as a Doctor Who type thing," McDevitt added.  "There are so many possibilities we don't want to definitively end the universe, but we can have storylines that have endings."

McDevitt explained the development team is constantly researching time periods for their future installments.  He told Edge their marketing point isn't the modern-day storyline, rather the historical setting the game takes place.

As for future settings, an email found in AC4 has been cause for speculation amongst fans about where the next installment will take place.  Unfortunately, McDevitt explained the settings found in the email are not necessarily places being considered by the development team.

"The email thread that's in the game, I wrote that very swiftly in an afternoon but I didn't realise that Kotaku would write like two huge articles about it," McDevitt told Edge.  "What a lot of people don't realise is that the time periods I picked were not necessarily the ones we were considering, it was just me parodying the ones that the fans had asked for back to them. So the fans generated that list, we didn't generate that list."

When Edge asked if any of the "Asssassin's Creed 5" speculation has been accurate, McDevitt responded:

"I will say that fans definitely think alike. We have the same goals for the series, let's say. I'll leave it at that. We always want to surprise."
