They do not need games out urgently... do you even keep up with how the Switch is selling? 😂they need to show us more of the confirmed games for 2019 and some unconfirmed ones so that people know what the lineup is for this year/updates on the current lineup.
That's just an opinion though. Yes it might be selling but its selling based on what it currently has. Wii was flying too then it died in the arse because there was nothing new coming that catered to new buyers.
Personally I am bored of my switch already. When I look at my PS4, every week there seems to be a new game or two coming out. I may not buy it but there is the option to buy it if I am bored. You get the impression something is always happening on the PS4 that meets everyone's tastes. On Nintendo systems we are at the mercy of Nintendo showing us something as generally 3rd party support is lackluster the last few gens.
That's not exactly true, huge boost in sales Switch recived because launch of Pokemon Lets Go and Smash Bros Ultimate, last month we had NSMBU DX, next month we have Yoshi and next week we are getting Direct with new release dates. Wii died after great fly because it had tons of casuals that left platform after all that motion controls, Wii Sports, Fit...worn off, while on other hand Switch from start is selling to much more core games oriented market.
You are right that that Switch lineup (or for any platform) cant fulfill everyone's taste, but someone can say same thing even for PS4, for isntance, PS4 dont have not much after Days Gone launch, on other hand it seems that Switch will have very packed year when comes to Nintendo games and exclusives and some interesting 3rd party games.
