Not seen you in ages around these parts, wonder why you chose to show up today. 

I am fine with this. The only reason I am buying the game again (already have it on PC) is for the portability. I have plenty of games to play until it releases on switch.

Meh, even if I like the game after trying the demo, it's a 3rd party game, so I wouldn't get it until half a year later when the price drops anyway.

You have unreasonable expectations if you expect most remasters on Switch to be on the same level as the ps4 and xbox. 

With the exception of Dark Souls, much of the delays can be explained. DQ was chucked up to the version of the engine used not being compatible during the game's original development. Now that the engine is compatible they have move the game over from the older version of the engine to newer release. Similarly, it is likely that development on Valkyria 4 started later, considering Switch was still new when the game was in development.

While your statement about porting PS4-based games does hold up for more graphically intensive titles designed around PS4, the Dark Souls port is based on the last-gen versions of the game. In fact, DS for Switch is being handheld by completely different studio than the PS4/Xbox One versions. There have been several ports of PS3/Xbox360 era games already that run and look better on Switch than on those systems. Based on the PAX demo, where areas like blighttown, which the last gen consoles really struggled with, were running fine on Switch. This indicates that this is not a case of the system struggling to run the game, but it could have to do with other things (maybe the online component of the game, or perhaps it was a business decision based on Nintendo filling up May with first-party releases which Bamco did not want to compete with).

Finally, I don't think your argument regarding sales of third-party titles hold up. We have had games like Attack on Titan 2 that have done fairly well on Switch, and even some late ports like Xenoverse 2. The problem right now is that we have very few major third-party titles that have had simultaneous releases with Switch. We know very little about how such titles would perform on the system.

I don't expect that.  But if they are going to take the easy way out, I do expect simultaneous releases.  If they were porting the PS4 and Xbone versions I would be more understanding.  But they are not.  They are porting the PS360 version with only the mildest of touchups and seeing as how the Switch beats the crap out of those machines no matter what mode you play in, I expected simultaneous releases.  In short, they can be ambitious and get some understanding with delays or unambitious and be expected to release on time.  They cannot simultaneously do both.

Why the hell people getting mad , it's not like the games was delay until fall or delay for a year . Be grateful the games  is coming in summer. It's not like everything will go according with plan, they might want to make the games run better and super smooth. 

and why did they have to delay the Amiibo as well? I want that thing more than the game...although I have pre-ordered both

This would have been a bigger deal to me if I didn’t have such a huge library of games. I’d much rather wait for a solid experience than get a rushed mess early.

Well they could have rushed it out early and in a bad state.. They absolutely made the right choice
