You're now assuming the PS5 is coming out holidays 2020. You're also assuming that a console launched a year earlier would not be more powerful than one launched after. Please correct me if I'm wrong, but wasn't the Xbox 360 more powerful than the PS3 in many ways, or at least on-par with the PS3's performance despite the year head start and the smaller price tag?
This is just one more instance of you letting your feelings get in the way of facts. Perhaps you should take your own advice on giving your own posts more thought.
Let me ask you again: what would it take to convince you that Colin is a Nintendo fan? What would he have to do?
The general consensus on the power disparity between the 360 and PS3 is that the PS3 was the more powerful console because its exclusive games produced better results. The big catch was that it was more difficult to get good results from the PS3 than from the 360, but the topic isn't ease of development.
If you look at the history of PS and Xbox consoles, you'll see a clear trend that the console that had a headstart was always the weaker one.
PS2 vs. Xbox: Xbox launched later, was more powerful.
PS3 vs. 360: PS3 launched later, was more powerful.
PS4 vs. XB1: Launched at the same time, PS4 was more powerful.
PS4 Pro vs. XB1X: XB1X launched later, was more powerful.
The logical conclusion is that a PS5 that launches earlier won't be as powerful as its Xbox counterpart. When both launch at the same time, it's up in the air which one is more powerful. But unlike with the XB1, Microsoft has already said that Scarlet will be about gaming and that power will play a central role in the development process.
With both consoles being more than one year away, it's up in the air which one will be more powerful. Therefore making a definitive claim in either direction (like Moriarty did) is not reasonable.
As for your concluding questions, he would have to consistently give credit to Nintendo when credit is due. But what he actually does is bashing. One such instance was another time you defended him, when he said things along the lines of "Nintendo messed up with Switch." Another instance was when he responded to good Switch sales by downplaying them, showing that he lacks the decency to admit when he is wrong. Those aren't the actions of a Nintendo fan, but rather those of a Nintendo detractor. Lastly, his legendary sales prediction for the outcome of the 3DS vs. Vita battle was filled with contempt towards Nintendo's console and its games.
In short, he would have to behave like a Nintendo fan in order for me to consider that he is a legit Nintendo fan. A token gesture on small things here or there doesn't undo the trolling on the big things, hence why I call it a disguise.
