Just a couple of quick thoughts on the "Sega Series X" issue:
As I said, I think is a big paradigm shift for both companies, if that rebranding in Japan is true. But, I fail to see, unless it's something for future generations to come, how is going to actually make MS gain market share on an established manner. I mean, you're just waving off your brand, so for future hardware pieces you're actually competing against that very rebranding you made, because people might not associate MS with this Series X console.
And then again, I think they're focusing on the wrong market for such a brass and possibly costly action, taking into account that the home console market in Japan has been on a steady decline for years, and is now, more than ever, Nintendo territory. Hell, even Sony doesn't have a particularly big stronghold there anymore. So, in a sense, I feel like it would be an effort kind of wasted there, when they should be focusing much more in Europe, in my opinion.
But of course, just my thoughts, I could be completely off with this.
