keep in mind PS4 hardware will be at least 3 years old when NX comes out so it isn't impossible for Nintendo to make a powerful console that still is slightly better than PS4.
I'll buy NX as far as the console is more powerfull than Wii U (except if it's an handheld for obvius reasons). that said I would buy it regardless of the power if they release on it the next Metroid game that sounds really likely.
All of that said the two games we know are speculated to come to NX are DQ11 and FF14, now DQ11 runs on UE4 but there's also the handheld possibility so it's a 50/50 FF14 on the other hand only released on home consoles so it's likely that NX will be at least more powerfull than PS3/Wii U
