That is not an argument, and just serves to illustrate my point - you don't like hearing the truth, so you try to denigrate an individual with sweeping generalizations. Either form an intelligent argument, or don't bother.
Sure, let's talk about sweeping generalizations for a moment!
And then we go on to this:
Why

?
Completely accurate in pretty much every way - PS3 destroyed Sony's profits from all gens of Sony PlayStation products, Sony as a company is now on very shaky ground and it's problematic how much longer the company can survive without extremely successful pillars, and the PlayStation brand seems to hold no weight at all - Vita is one of the biggest bombs of all time, PS3 flopped versus past PS systems, PSP died in the USA and never recovered.
At this point we're beyond trying to act like this is hyperbole - either people can start accepting the harsh reality that we're in, or they can create some sort of intelligent argument as to why I was wrong.
None of this is actually related. You go from talking about how no one would have
any reason to own a PS3 over a 360 (as if FFXIII would have shifted the install base more than a million or two anyway), to talking about how the PS3 under-performed versus the PS2 and the Vita bombed. You're shifting the goal posts. No one is saying that Sony isn't in a tougher position than they were during the PS1 and PS2 era, but that's neither here nor there to why your original post is so outlandish. Predicting MGS4 would hit the 360 is just icing on the cake.
For instance, if we ignore the idea that FFXIII would really trigger the kind of scenario you laid out, even ignoring that, you're projecting a timeline that simply doesn't exist. You say it's going to be this gens gamecube, and that there's no reason at all for anyone to get it over a 360. The fact is that the math just doesn't add up.
This isn't hyperbole, the isn't fanboy drivel, it's math. Where's the beyond normal degradation in sales in the PS3 to cause the $99 firesale? You can't make the charts and have them line up even remotely. beyond that, for FFXIII going multiplatform to have been the end of the PS brand, you'd have to see the 360 moving into a position of true dominance.
When in fact that never happened! We've seen both consoles remain extremely competitive with one another, with the PS3 still outselling the 360 when launch aligned and on a worldwide basis.
The core issue is that, if we're to take your post literally, that there is
literally no hyperbole, well at best you're the living example of compounding logical fallacy's to desperately try to save face, and at worst it's an example of cognitive dissonance.
If you read that post and honestly can't understand why it;s outlandish or why people laugh at it? But honestly it's just a bit of both.
Your post is laden with things that were absurd as of the time of writing, never-mind the prognostication into the future that ended up beign entirely incorrect. Let's be honest for a minute here, that shit is what you read on gamefaqs, and you don't need to be a fanboy of any stripes to see it.
