Can we stop talking about that idiotic rumor now? It's wrong on enough things that the unprovable bits shouldn't be treated as gospel. I'll go through it so maybe we can just stop pretending it deserves to be repeated.
The first one gets the name right for MHXX. We know that in Japan the game is completely exclusive to PS4, so the veracity of the next bit is questionable. We know MH5 is not open world, so that next part is wrong. There will be missions and town hubs. The next bit cannot be proven or disproven, just like any indications of internal strife or backroom dealings.
The next picture is more obviously bullshit. MHW is being worked on by the core MH team.
MHW will not be removing any weapon types. Impressions of E3 goers who saw the demo did not reflect significant reductions in complexity of the combat. The rest (well, all of it really) is baseless speculation.
The third picture is just doubling down on the shit we know is wrong. We know the game has/emphasizes gathering, though it may be streamlined. No evidence of QTEs in the footage shown. They showed a new monster, but no shit they'd bring in legacy monsters. Not open world, no local co-op is a no-brainer. Coming out on xbox.
This rumor is bullshit. I'm sure someone else has already made this post, but I felt compelled after seeing how many people assumed MHW is westernized shit because of it, or that a shadow team is working in secret on the REAL MH despite the literal assertion from Capcom that it's the next mainline entry.
The first picture hardly has been debunked, in fact all we know only makes it seem more true:
-XX name was proven correct
-MH5 might not have been final, could have been negotiated (Sony seemed to make a deal for FF XIV to be numbered, exclusive game when XIII had come out not even that long before) and Capcom got cold feet not wanting to alienate their core base (because that would have been really stupid no matter how much money Sony was trying to pay for a numbered exclusive aimed at a Western audience).
-World being exclusive on PS4 in Japan and not on the Switch, while being on PC and Xbox, makes the next two points seem plausible, they paid for exclusivity in Japan since they are "desperate for Japan". And of course they would forbid Nintendo because they want to steal their base for the game, especially if the part about trying to make it MH5 is true. In fact, part of the naming of MH5 could be supported by the original team being involved. Most here have seemed to assume that to be true due to who is involved, despite not having a number.
-Gameplay could have been speculation about open world, such as if it's doesn't have the same sort of "arena" layout of the map but open areas you can travel across without loading. Timers seem to be gone. Missions can be formatted differently. We also don't know how much of the old combat with remain, but this seems more action focused from what we've seen. Music is taken from the cooking seems to be a change to make it more accessible to the west, we haven't seen characters like Felynes or more fantastical, light-hearted additions. Combat could have certainly been streamlined, simplified, or altered from the traditional formula to appeal to new fans.
-MH Portable is still stuff we have 0 knowledge of but if it exists, it would make sense that it was indeed MH5
The second sounds like lots of speculation (always has) but if it is indeed the same person it could fill in a lot of the blanks about what is going on in this situation.
