OK, lets look at some facts, lotsa IPs that were exclusively on PS1 and PS2 later become multi platform games last and this generation, that goes for FF also. Fact that they said for FF7R "play it first on PS4" screems multplatform game that will just be relased 1st on PS4.

Actual opposite, FFVII 7R could easily sell around 1m copies on Switch, while costs of porting on Switch would be recovered with just 200-300k copies sold on Switch.

"Play it first on PS4" means exactly that, it will be just released 1st on PS4, that doesn't mean they can't announce game for other platforms in meantime.

Evre game could be ported on almost every hardware, Wii that was 20-30x less powerful than PS3/Xbox360 received ports of PS3/Xbox 360 Call of Duty games.Switch is around 3-5x less powerful than PS4, and not only its very easy to work with Switch, but also games uses UE4 engine that its very scalable and its supported by Switch.

"Play it first on PS4" means exactly that, it will be just released 1st on PS4, that doesn't mean they can't announce game for other platforms in meantime.

Snake was in Smash for GameCube and actualy GameCube had Metal Gear game, Metal Gear Solid: The Twin Snakes.

Metal Gear Solid 3D: Snake Eater also came out a couple of years after Snake in Smash, but Nintendo had already collaborated with Kojima by that time on MGS: Twin Snakes which Nintendo had their own 2nd party work on (Silicon Knights). 

Speaking of which I think you'll see a lot more Konami content on Switch. They're probably pretty happy with those Bomberman R sales. 

EDIT: If you actually go back to the 3DS unveiling E3, the "Metal Gear Solid franchise" (not just MGS3) was supposed to be on 3DS. I'm guessing the PSP MGS series was meant to continue on 3DS perhaps, but Konami didn't like Snake Eater 3D's sales and/or became enamored with mobile. But at the time it even got the loudest applause from the E3 crowd:

It might come to the switch but showing any footage for the switch at this year e3 will not happen. Ps4 version needs to be finished first before they start working on the switch version.

You don't know any of that. Unless you have the contract in front of you, you can't have any idea what the terms are. 

So instead of working hard to get the game out for the ps4 some time next year, they are now also working on the switch version and delay the game even further? I can say that ain't happening and therefore there will be no footage of switch version until the ps4 version is finished.

Second team can work on Switch port regardless PS4 version and without effect on PS4 version, and ofcourse PS4 version of game will be 1st release in any case.

Anyone remember how they first announced the FFVII remaster coming to PS4 and it was the original PS1 version?

I think this is what may happen here.

Great. I want to the original FF7 on Switch. I think the FF7R could happen too. Though I will say this right now -- I don't think that game is going to be as good as people think it is. They're going to change a bunch of shit that's going to piss a lot of people off. 

Just imagine meltdown on internet if Nintendo console relly gets main FF game (it would be 1st time after SNES) and actually Remake of probably best PS1 game and espacily Remake of FF7 game that lotsa people thought its was 1st party game. :D

We already seeing here points that Switch won't get FF7R because FF7 was PS1 exclusive. :D

Well, we've seen stranger things happening, so we can't completely rule it out.

That said, having the game at E3 on Nintendo's conference/Direct is very, very unlikely.
