Sony has updated its PlayStation Meeting website with a 'PlayStation Evolution' video detailing the creation of PSOne.
Sony is expected to unveil PlayStation 4 at the New York City event next week, and the hardware video series further hints at the platform holder's intentions.
Codename 'Orbis' has been the subject of an increasing number of high profile 'leaks' in recent weeks, including more than one alleged system specifications dossier.
According to a recent report, PS4 will support "multi-user simultaneous logins", allowing multiple users to be signed into accounts simultaneously on a single console.
The new PlayStation controller will feature a PS Vita-like touch pad - which CVG understands can be 'clicked' - and redesigned anolog sticks with concave indents. The controller will also include an illuminated panel which behaves like a Move controller.
