The games you compare this to are nowhere near as big and ambitious as DQXI. The kind of issues that arise for one certain game isn't necessarily the same issues that will happen for another. And besides, Square-Enix could have customized their version of the engine, for all we know. Making it possible for other issues to arise.

They did say that but that's precisely why people are confused and frustrated.  When did they start these discussions?  When 4.16 launched?  When the PS4 version went gold?  Those are 11 and 9 months ago respectively, so where's the progress?  Why won't they show it?  Or did they start work very recently?  Cause that would be quite an alarming discovery.  No matter how you slice it, it's not a good look.  Either they have made progress but refuse to share it for whatever reason or they have none because they just started in which case what were they doing from the 4.16 on?  Waiting for the PS4 version to go gold?  Ok so what about since then?  

Like I said, it's not that PS4 got it first, that makes sense.  But the fact an unsupported engine like idTech 6 designed explicitly for taking maximum advantage of the PS4 and Xbone will have 2 ports on Switch before an Unreal Engine 4 game that is far from the most demanding game built with that engine is quite a confusing annoyance.  The fact that at this rate they will both be out before we even have a screenshot of the Switch version of DQXI is baffling.  

And also, unjust or no, this kind of treatment of the version also makes people increasingly concerned that it's going to be a bad port with minimum effort.  I personally don't believe that, I think Square is just being the same company that *still* hasn't finished Kingdom Hearts 3.  But it's a feeling a lot are going to have.  Transparency would go a hundred mikes towards smoothing things over.

Lol, they basically said they announce game for NX even before we had Switch name, so yeah, it was annuced too early, and they later basicly said that all version will be released in same time.

Ok, you are right. Switch supported the engine even before being released. So there is no excuse left why SE still can't show anything from the Switch version. At least, we can assume that they are working on the PS4 version even longer. Granted.

Are you kidding? They announced support for the engine before the Switch came out, yes. But the first actual version supported came out in may 2017. That's after the console released.

They could.  But given the fact DQXI PS4 exhibits not a sinlge ounce of customization work and that was, in their own words, the prioritized version, I highly doubt it.

Also if they customized it to work with Switch that would contradict with their line about waiting for compatibility. 

And yes, Snake Pass is not on the smale level.  But it isn't a 2D platformer either and has its own unique challenges that DQXI does not, notably in its physics simulation.  It was also ported in a month though, Square has had eleven times that.  Or nine times that if we assume they started after the PS4 version went gold.  And from what little in engine visuals we have, Shin Megami Tensei V is far from a slouch.  And again, it *started* development in 2017 and has something, be it very little, to show.  

Edit:  also Sumo Digital is an ant next to Square, another point to make about Snake Pass.  Yes, not as ambitious.  But then it was ported in a short time by a small team.  Square has had a long time and is a juggernaut.

Well, you know better than the DQ XI developers themselves. So I guess there is nothing I can say to make you see a possible side that's different from what you offered here.

Yes, at this point I'm rather making fun of SE more than anything else.

Well, now I had more than enough fun with this, I'm not going to bother anymore. I think it's dissapointing that they bring very lame excuses like this. On the other hand, I can also see your point in that we can't know the whole picture. So it's just a waiting game now for those who wait for this game on the Switch.

Yet games like SMTV have teasers and a trailer out showing the game and its on the same engine DQXI people have not been shown a single thing so they do actually have a point here.

The point could be that they don't want to show a version that will undoubtedly look worse/inferior to the one currently getting the hype?

Don't you think it would make many Nintendo fans call the port a lazy one like they so often do? Heck, there's already an outcry from the vocal minority over conjectures and what ifs. Imagine then?
