Yeah really. Very few people heard about XGC and party chat on consoles before this gen. And now everyone expect them to be standard next gen. So yeah, next gen will bring something more advance and much more useful than this gen OS wise and Competitors should be aware of MS since making OS is their core business. It´s very short sighted to assume that 512MB RAM from a hardware company like Sony to match 3GB RAM of MS and company which specializes in software development. I don´t know what´s the next big thing, but i´m sure that you don´t want the Orbis to be way behind again with regards to functionality to the Durango. 3GB OS for Durango will definitely not be just for show.
You do know there was a party chat system on the og xbox right, it was just the next logical step making it part of the whole dash rather making it only usable outside of gaming. Lets not forget as well that it didnt launch in the state it is today it was one on one at the start.
