See, this is inherently false.
What actually happened was the internet exploded against Microsoft and the Xbox (One) and Sony fans/fanboys/enthusiasts/evangelists had an absolute field day wrecking havoc on what Microsoft (deservedly) brought upon themselves (especially after a generation where Microsoft came out of nowhere and knocked Sony around for so long). From TVTVTV to specifications to Don Mattrick to used games to Kinect 2.0 NSA spygate. The people that were actually Xbox fans were called out almost everywhere besides Xbox-centric websites, and even labeled shills at times. That eventually died down but the stigma remained for a long time until Microsoft started righting the ship.
From a rational standpoint, it felt like Xbox fans and even the media at times were just being defensive, and rightfully so. I mean, the FUD spread so badly, people would come to my store and be surprised at the Xbox kiosk because they assumed it had Wii graphics from what they read online. Wii graphics. Seriously. I had trouble selling 1080p TVs in 2013 for anything lower than 46 inches, and I made freaking commission, so imagine that. It wasn't THAT much of a huge visually between both consoles and frankly what should have been a bigger deal IMHO is performance, but I digress.
Scorpio is so, so much more than "true 4k." GDDR5 upgrade, 4GB more RAM, 4K BR drive, much better GPU and ever so slightly better CPU are really great things, but this is what Sony fans will never understand: they went from having the "most powerful" console for 3 years (something that they downplay today whilst talking about games being #1 even though the goalposts for years have been power, graphics and 1080p) to having an EVEN BETTER console because Sony was reactionary to potential PC converts as well as knowing that PS4 would be a terrible way to push PSVR. So, Sony gamers and fans went from having a better console to an even BETTER one, and Scorpio is bypassing them both, and going to be the undisputed best console to play multiplats which account for 95% of the libraries for the next 3 years. And when Sony releases the PS5 in 2020 (maybe late 2019 but I doubt it for many reasons) Microsoft can have a Scorpio2 ready to release a year after and continue the same thing, which will be fully backwards compatible even with your 360 games, something that we don't even know if Sony will do yet.
So, it's not "true 4k vs fake 4k" in their minds, it's most likely what I wrote. And this isn't even taking into account all the things PS4Pro does wrong that Scorpio does right, technically wise, like 1080p downsampling or playing 4K blurays (which was a big, big thing for the PS3).
All Microsoft needs to do is three things right now:
Build first party portfolio and Xbox/Win10 exclusives
They will focus on this next since they have hardware already where they want for the coming years
Make internal publishing team to allow every game not first-party/contracted by Sony/Nintendo available on Xbox and or Win10
They just rebranded MS Studios to MS Studios Global Publishing, so maybe this is in the works? I.E., all games available for the best console to play said games, including Japanese games that won't fund a port themselves. Expansion of ID@Xbox which has received phenomenal praise from devs? Likely to start all digital, maybe not physical releases, just sending teams over to port? Thoughts?
Continue to make Xbox Live the best place to play
They have been doing this since console launch and the inclusion of Clubs and LFG have been amazing XBL additions, as well as MS Software Ninjas making the atrocity that was XB1 launch dashboard into what it is today, which is infinitely better. Just continue what they're already doing here.
Anyways, my 2 cents. More like 25 cents

I'm actually a lot more excited for Switch this year for a couple of reasons but I hope Microsoft has a killer E3!
