How long will Sony support the idea of developers making console games exclusive to one platform? It looks like that answer may depend on how much third-party publishers want to make their games exclusively available to PlayStation owners. In an, Sony Worldwide Studios head said that Microsoft must continue to ensure Activision continues making its multi-platform games available on PlayStation.
Sony hopes Microsoft will stick to its promise
Sony wants to keep working with Activision and other publishers that offer games for both consoles and PCs. However, it’s up to Microsoft whether those companies will be allowed to continue publishing games on Xbox as well as PlayStation. Microsoft also said they are continuing their policies toward keeping multiplatform going forward.

Sony says Microsoft has spoken very clearly on this issue
Activision won’t be blocking PlayStation users from accessing its games. In a conversation, Sony Computer Entertainment president and global CEO said he had spoken with his opposite number at Microsoft about Activision’s controversial decision to lock players out of Destiny’s beta. It was their second chat on the subject in three days, which suggests that Sony isn’t just humoring one of its biggest third-party publishing partners — it really means it. Microsoft Gaming CEO has publicly stated that he believes that for consumers it is better for them if more people have access to their content than fewer people have access to their content.
Sony seems confident Microsoft will stand by their commitment
Sony fully expects its business partners to continue to ensure gamers have a vibrant, fun and smooth experience at all times. As always, they can only speak for their company and not for their competitors. That said, Sony supports its partners investing in new technologies but do so while respecting choices made by consumers. They believe in responsible businesses competing vigorously to provide consumers with great games is good for the industry.
