While Xbox 360 and PS3 both have 512MB of RAM, it has been rumoured that Xbox 720 will feature 8GB of RAM, and recent comments by Crytek CEO Cevat Yerli could be seen to back up this theory.
Asked what he'd like the platform holders to factor into new console hardware, Yerli told VideoGamer "you can never have enough memory".
"Memory is the single most important thing that is always going to be underbalanced - I've never seen a console where the memory was the right balance.
"Xbox 360, underbalanced. PlayStation 3, underbalanced. Simply because memory is the most expensive part, hence I wish there would be cheaper ways of doing memory so that memory doesn't become an issue anymore."
He added: "If they find ways to cheapen the cost to a degree they could triple or quadruple their memory. Just say, 'Hey we're going to have 32 gigs of memory'. That would be quite amazing because memory can do so many more techniques and tricks."
Last year Crytek's R&D principal graphics engineer, Tiago Sousa, said he'd really like to see next-gen consoles feature a minimum of 8GB" of RAM.
"My finger-pointing at Microsoft/Sony would really be on the memory side. It's way too low, and the biggest crippling factor from a visual perspective," he added.
Xbox World has been at the cutting edge of Xbox 720 coverage and over the weekend, ahead of the release of the mag's final issue, we published its huge 'Xbox 720: everything we know' feature, which does its best to expose Microsoft's next-gen console plans.
