GC was their worst selling console till date, and after GC Nintendo changed strategy and we had their best selling console till date. Now Wii U is fair worst selling Nintendo console with actualy catastrophic sales numbers, so of course that Nintendo will work much harder, and change lots thing in order to have much more popular product than Wii U was. We also seing losta changes reagardles Nintendo, internally and externally.
So yes, it's very unrealistic to expect that multi bilion company that survived on market over 100 years will act like nothing happened after their worst generation and easily their worst selling console ever.
.... and the SNES was their worst selling console to date, and at the time, it was their worst generation and easily their worst selling console ever
.... and the N64 was their worst selling console to date, and at the time, it was their worst generation and easily their worst selling console ever.
.... and the GC was their worst selling console to date, and at the time, it was their worst generation and easily their worst selling console ever.
It's a very similar situation with handhelds.
See I'm looking at the bigger picture. You're looking at the Wii and not treating it as the anomaly in Nintendo's history that so far it has been. It's more realistic to expect Nintendo to make a console that sells at or around GC levels (because let's face it, the Wii U sold worse than anyone could ever imagine, and it's unrealistic that Nintendo will make anything that ever sells worse than that) than it is to expect Nintendo to sell a console that's at or around Wii levels.
But let's be clear - GC level sales are still terrible.
No exatly same thing:
-SNES was best selling console of that gen
-N64 was second best selling Nintendo console of that gen
-GC was worst selling console of that gen, far behind PS2 and around 10m behind Xbox. But point is that after GC Nintendo changed strategy that lead them to their best selling console ever.
-Wii easily best selling Nintendo console, with 101m.
-Wii U curently around 13m, LT most likly around 14m. Huge drop from previous 101m, easily far worst selling console this gen and worst selling console ever for Nintendo. Same like they done after GC, Nintendo will definatly make some big changes and strategie in order to have much more popular product after Wii U.
To be clear, I dont expecting that NX will have neary similar numbers like Wii or that that NX will have similar appeling like Wii, but I am 100% conifident that will sell much better than Wii U (like you wrote, it's unrealistic that Nintendo will make anything that will sells worse than that, I dont think they could do that even if they want), I relly dont expect less than 20m in worst case. Its way to early to guess what sell numbers will NX have, but if only Nintendo adress huge mistakes they done with Wii U (all points they doing that) like terible and missaunaderstood marketing, weak launch and 1st year lineup, unapiling gamepad, not competitive price...NX could have sales 20-50m.
