'Destiny 2' is expected to sell between four to five million digital units on PC and console within the first three months of sale.

That's according to a new report by SuperData Research which analysed the performance of the original 'Destiny' game - which was released in September 2014 on PlayStation 3, PlayStation 4, Xbox 360, and Xbox One - and have taken the early September 6th launch date into consideration.

They said in a release: "SuperData evaluated the performance of Destiny 1 on console and how it compared to other AAA titles that launched during the same time period.

"The forecast also takes into account the expected early September launch date of the title, the impact of a Battlenet release on PC and macro-level digital download trends."

'Destiny 2' will be the first game in the series to be played on PC.

Sam Barberie, vice-president of product and business development at SuperData Research, said: "As the buzz around specific titles continues to grow within the digital gaming industry as a whole, the [SuperData] Forecaster offers a unique starting point for those thinking about sales scenarios.

"By pairing this with the SuperData Arcade, the digital gaming industry can now have a clearer picture of what drives sales success and how their future releases could gain an advantage."

Earlier this month, Activision CEO Eric Hirshberg insisted Destiny 2's long-term support will be more robust than its predecessor after he was left disappointed with the way 'Destiny' was supported with expansions after it was released in 2014.

He said: "I have not been happy with the cadence [of new content]. We got a lot right with 'Destiny 1', but one of the things we didn't do was keep up with the demand for new content."
