there is absolutely no way you can calculate it since the years the ps3 has been profitable it was merged with other division. and you tend to assume alot in your post "The Vita was not yet launched and the Vaio business was going strong according to the report." the vaio bussiness was never that really profitable for sony and they were working on the vita R&D by that time.
