PlayStation 4 is likely to be released in the spring or autumn of 2014.
That's according to tech site SemiAccurate, which also claims to have heard from Japanese speaking sources that Sony's next-gen console project is codenamed Thebes, rather than the previously rumoured Orbis.
"Other than it being an AMD CPU and GPU, we don't have much more specific details," the site says.
"It is said to be a 28nm part, likely fabbed at Global Foundries or IBM for the first run, and out after Oban. That would most likely be the spring of 2014, but it could be fall of that year too."
Oban is supposedly the name of the developer test system chip being used for Xbox 720, or whatever Microsoft's next-gen console is called. SemiAccurate reports that the console's internal codename is Kryptos, and not Durango, as widely rumoured.
The site says Oban is still scheduled for mass production wafers before the end of 2012 in preparation for the console's planned September 2013 launch, but that previously reported problems like "painfully low" yields (a measure of functioning devices) could delay that timeline.
Xbox World has been at the cutting edge of Xbox 720 coverage for over 12 months and yesterday, 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.
