Its not too soon, every Nintendo handheld had some kind difrent type of revision around 2 years after launch, and Switch hardware is essentially handheld and has even more opportunities for different type of revisions than 3DS. Point is simple, offer different price point of Switch platform, for instance you have 3DS for $80, $150 and $200 and 3DS is dying fast, so smaller and lower price point revision for Switch totally make sense, stronger and more pricey Pro not that much curently.
But main point of this rumour is not if will be Mini or Pro, but point that new version of Switch is coming next year in any case.
But thats the problem.The Switch is not a handheld, its a hybrid.You could say that since its half handheld, it would inherit not only its traits but also its overall market strategies.But the same can be said about its home console side, and we know how many revisions they had, and how often they are.Personally, it dosent make sense.Nintendo would be wasting an Ace they would have in their sleeves too early instead of using one that is more natural at this stage and would have a far bigger impact without a secong SKU in the market, which is the price cut.Not to mention that, if they introduce the Switch Pro(Because it wont be a Switch mini that is entirely handheld, thats never going to happen, just plain wont) after the price cut, they can make more people double dip, than if they release said SKU before the price drop.The facts simply dosent add up.
I have no doubt in my mind that Nintendo is already hard at work in an improved Switch, but I dont think its comming in 2019 at all.And about the rumor:No matter that the report is about Nintendo making something, if people want to talk about wether its a Pro, or a Mini, or a Switch Station or whatever, with the details that there is on the report, its simply too vague to make one conclusion or another.
My (locked) thread about how difficulty should be a decision for the developers, not the gamers.
