The multiplayer game sessions will still be purely Peer 2 Peer. It doesn't matter if you are connecting to a data server to pull down the latest information. That is a given since its an Online-only game.
PvP should be ran through dedicated servers. My machine connects directly to your servers and not someone else.
The money maker for Microsoft and Sony in the console business is online subscription revenue, digital sales for the Xbox Store and PSN, and third party licenses.
A very small minority of PC gamers would be willing to buy a whole new machine, pay to play online, and continuous buy games from a console digital store. The vast majority wouldn't even bother.
If someone is just buying a console to play a few exclusives here and there, Microsoft or Sony aren't making much money off you.
By lower the barriers to entry, Microsoft can now sell games directly to a much larger audience who wouldn't bother getting an Xbox, which in turn gives them more potential revenue.
Nvidia's, along with AMD's, drivers only support traditional ".exe" programs. Since Rise of the Tomb Raider uses DirectX 11, a profile has to be matched with the ".exe". Since there isn't one for the Windows Store version, since it uses UAP instead of .EXE, it currently doesn't have SLI/Crossfire.
In a DirectX 12 environment, there is no need for a driver profile. The API already has native support. I'm sure Quantum Break will support multi-GPUs since its DX12 Only.
The game being exclusive to the Windows Store is fine with me. I'm not a fan of having every game using the same service, I like things decentralized and to me, that is one of the pros of PC gaming.
Also don't see any inconvenience on using multiple clients. I have all my gaming clients on my taskbar. Just click and launch game. Done.
