well, we already know due to the new CEO and their recent business moves that they are in fact investing in network and services. they already have PS Now, and you believe streaming is where the hardcore market is going? im not really following your logic.
Sonys approach to services is trying to sell you more subscriptions to non-gaming type stuff. Vue, Spotify, Crunchroll, Video unlimted, Netflix etc. Great for a casual audience, but not hardcore facing. PSnow is a half hearted initative that has had la whole generation to find its niche and still hasnt.
Microsoft is pushing Gamepass, EA access, Mixer, Discord :- Specfic services related to hardcore gaming. They have bought Havok to ensure they have fingers in the middleware pie.
Like I said, I dont consider Sony "doomed" by any stretch of the imagination. But they seem ok with ceding more of the Hardcore ground to Microsoft. Thats fine at the end of this generation, but unless Sony have some massive surprises instore, the start of Next gen Microsoft is gonna be off to a running start and Sony will have a hard time building the same momentum they did this gen.
