Psygnosis basically ceased to exist when Sony acquired the last of its stock in 1998. Psygnosis was an organisation of administrative personnel who controlled more than one studio; once Sony owned them entirely and made all the decisions, Sony was the organisation. No more Psyggy. Studio Liverpool was one of the studios Psygnosis controlled, it was not Psygnosis itself.

Anyway, that's the way I parse the logic.
