@qwza: I have heard those rumors too. And I think that's quite plausible. The WiiU already provides a system like that, just with having a fixed base connected to your TV, but can play many games over wireless on the controller with the integrated display. I can imagine a future Nintendo handheld console with an HDMI out for optional gaming on the big screen. At least I think that rumored new console is more interesting then PS4&XBOne for me.
@topic:
I have played pokemon go a bit now (trainer lvl 16).
My experience so far: it is fun going out visiting stops, conquering arenas and searching rare pokemon. But with every further levelup, the fun moves a bit more into the background. You basically grind your trainer XP by catching the same common pokemon (pidgey, caterpie, weedle, rattata) and evolving them once you have enough candies.
Fighting is really annoying, no real tactics needed, pokemon have a base and special attack and you can evade. That's it. Increasing the strength of your pokemon by fighting? Nope. You use stardust and specific candies instead.
Overall I think the mechanics of the game are OK, but not what I would like to see in a pokemon game. Also the lack of social interaction through the game, something like a chat with players near by, a friends list.
And then there is the item mechanic. Either you are lucky and live in the center of a relatively big town, then you have easy access to lots of pokestops and arenas, or you are as unlucky as I am and have no arena and only a single stop in the whole town. Finding Pokemon and visiting stops&arenas forces you into cities, going for a walk in a nearby forest for example doesn't help in the game. What also eventually happens: you run out of balls or potions, only solutions the are slowing down your progress in the game (because you are not always lucky enough to have the time to travel to the next city with enough stops), or buying items for real money.
I finally reached this situation: I am out of pokeballs, have no stops near by, want to play, but don't want to invest money at this point. Because with increasing amount of XP needed to level up, every pokemon caught is worth less and less. And so are the balls.
I believe the hype around this game will settle in the next few weeks, because eventually everyone will run into a point where progress starts to really take time. No autumn & winter needed for this (although worsening of the weather will definitely have it's impact on the players).
The developers will need to implement some neat features to the game in the future, to keep the userbase up and motivated.
