People claiming that it's a new game altogether just because of the BotW Link...
You poor naive creatures of hype. XD
Are you forgetting they added new characters for Mario Kart 8 DX, Pokken DX and also for Hyrule Warriors DE?
And they added BotW Link to Hyrule Warriors too, is Hyrule Warriors Definitive Edition a new game just because they added BotW Link?
They could very well just have ported the Wii U version and added a few new characters to the mix to make it nor such a shameless port, as what they did with previous DX ports.
The fact that both BotW Link and Splatoon characters were added doesn't mean specifically that it is an entirely new game.
Hell, BotW Link might even just be a new skin xD
But being Nintendo it would be better if they add him as a separate character.
Also, the point about the Copyright goes completely null when you check out Mario Kart 8 Deluxe backcover:
Check above the serial number, it clearly says
©2017 and not
©2015-2017.
You guys REALLY need to ease up on the hype just because they show a couple new characters.
Every port of a previous Nintendo IP made from the Wii U to the Switch has added a couple characters at least.
Don't get your hopes up.
Why didn't they show gameplay then?
That's easy, marketing strategy.
In each Direct people spam the chat endlessly claiming for Smash for the Switch, and what better way to create hype than to just tease it and let people speculate. Creates more clicks and news about it thanks to the speculations, which also widens the amount of people that will get to know about the product.
Don't get me wrong, if it ends up being a new game altogether, good for you all, but seeing how little time there has been since Sm4sh on Wii U/3DS and the Switch release, we are talking perhaps 2-3 years tops, and a Smash game development usually goes from 5 years and up.
Just don't get your hopes up as much, that's all.
I personally don't give a shit about Smash, but I can see why the hype is all about.
