So, wait, what's happening? Essentially, Sony is moving its network business out from under the gaming wing and bringing it up to the parent company level. This is a different path than the one laid out a year ago, which suggested SCE, as then operator of the network business (think: PSN), would begin to play a larger role in the unification of the company as it pertains to an online strategy. Instead, the "new" Sony Computer Entertainment will have a slightly more narrow focus, "mainly consisting of the planning, development, manufacturing and sales of home-use/portable game consoles and software," according to the reorganization announcement; and Sony Online Service, including the proposed expansion of PSN IDs to non-gaming Sony devices, will seemingly be handled by a new division (but possibly the same personnel) within the Sony parent company.
Though listed as the "Representative Director" of the short-lived SNEP subsidiary, Kaz Hirai will presumably remain in charge of the PlayStation division now and after the April 1 merger. Sub-divisions SCEA and SCEE are unaffected by the reorganziation.
