If the NX goes Arm route, and go mobile having ps3+ performance, then it will ve very close to high end smartphones and tablets. Todays Smartphones and tablets have graphic cards that have ps3 performance. Two years from now, they will be even faster. Casual gamers will play on that platforms, not in NX. Maybe japanese will. Hardcore gamers will be on MSft or Sony side.
If those same hard core gamers are so concerned with power why don't they just go with a PC. Hell, hardware is cheap enough that you could make a $500-600 computer and get the superior experience. I never understood that about the people who ragged on the Wii U's lack of power.
I would also mention that steam machines are also in Sony and Microsoft's rear view mirror. It's not an immediate threat, but eventually more games will be compatible, the operating system will be improved, and with the right price cuts, they will begin to increasingly siphon off sales long term from both Microsoft and Sony. The console market is going to be very crowded.
A lot of hardcore gamers, wont buy a PC.
1- you need a more expensive PC if you really want to see big differences in graphics.
2- Most parents that dont know anything about PC just go to the mall or supermarket and buy a console.
3- Consoles are more user friendly. you just sit on the couch or bed and press a button to play. On a PC you have to enter to windows, enter to steam, check drivers, put big picture, and then play, not so friendly in the living room.
4- You have to find someone that build a pc for you, else its very expensive.
a console is like apple iphones, very easy to use, not much to set up, almost like buying a tv.
And I dont get the point on buying a steam machine. I think its just better to buy a cheap pc to do streaming and that can play a lot more native games.
A console gamer will buy a Sony, Microsoft or Nintendo Console, wont buy steam machines.
Now, on the power.
IF Wii U had the same power of the PS4, then a lot of third party will develop for it.
Also nintendo would be able to make bigger games and with better graphics diferentiating itself from mobile gaming.
Nintendo had once the most powerfull machine of its time, the Nintendo 64, but now they want to earn money selling shit hardware. It was great with the wii because there were no mobile gamers, they introduced the wii mote and they were selling Wii at 250 USS instead of 500. Now its another ballgame. And if nintendo makes cheap hardware that compares to mobile, they will fail horrible. They are more concern about making stupid amiibos that had almost nothing to do with the hardware to play the games or the great games they used to make like ocarina of time. Its almost like making dolls for fanboys instead of making great platform and games.
