I'll have to disagree on some points here, but first I will agree on the mentality of gamers have changed somewhat. There are still "brand loyal" gamers out there (Gaystation is a word I often hear from the anti-Playstation crows even today...And Nintendo iz for teh kiddiz). Such is life.
Now! The three (perhaps soon four) are all after the same gaming market. BUT! With the PS5 and Nextbox just around the corner I am sure a lot of third parties are working closely with them for their next big hitters. Wouldn't surprise me if Cyberpunk 2077 would come to those systems. And when that happens (it's not if, it's when) then today's Switch will be forsaken from most third parties apart from indies. So NIntendo HAVE to soemthing to compete. I wouldn't be surprised if they beef up the Switch like with hte New 3DS but we can still use the joy-cons and dock etc. Could be a cheap way to upgrade.
Call it a "Switch Pro" or "NEw Switch" or "New Switch 2" or "Wacka Wacka Bing Shackalamb". The name is not the point, the point is that Nitendo have to do something when the competition gets heated again. And if it's 100% backward compatible with the original Switch I can see it be a nice extension. And now tat Nintendo are venturing into VR, a "New Switch Pro Ultimate 2" could truly happen. I don't think they will drop the hybrid idea any time soon, but they have to follow the competition anyway. Times are changing and so is Nintendo BTW.
Oh well. We'll see soon enough I guess. Next week we might see what Google are up to and that can be big for the industry. The PS5 and NextBox will also be shown this year also. In any case, it's very exciting to be a gamer these days.
