If a person walks into a dedicated game store and sees the competition flourishing and the other not, I know what I am buying.
You have just answered it, clearly Nintendo to tight arse for me to have access to physical games if I have to rely on digital catalogues.
You just spewed a load of waffle that said nothing to try and sound like you're right stores decide themselves what to stock not companies, people mainly buy digital or from online stores like Amazon as it's far more convenient hence why so many retailers are taking big losses on games sales an example being Gamestop who had a disastrous loss last quarter which is why your shelf space argument has little bearing on a platform's library other than who is still going to the said store and that dictates what the store decides to stock up on.
With my work I end up going to many stores, it is the same story.
Irrespective of what is happening online, under your logic if more and more people are buying digital or on amazon, surely all platform sections would shrink accordingly in terms of shelf space. The shelf space arrangements I mentioned have been around like that long before online shopping was a thing in Australia. If these haven't changed clearly it just shows that PS4 has more games that are worth putting on shelf or Nintendo don't want to pay for shelf space.
OK lets roll with your online idea, i checked online for one of the major retailers here in Aus.
Ps4 has 90 announced games coming in 2019, with 50 confirmed release dates
Switch has 40 announced games coming in 2019, with 15 confirmed release dates.
Surely you can see why the Switch looks like its in a dry spell to a gamer that has other tastes then just Nintendo games?
Hell I ain't even worried about 2019 too much its the fact we are not seeing any 3rd parties really saying they gonna go full swing into switch development either which is concerning.
