I see four possible scenarios:
1. Ps4 neo sells well and Sony's success continues.
2. The masses decide to skip ps4 neo in favor of the more powerful Xbox Scorpio and the Xbox Scorpio go on to outsell the ps4 neo until ps5 comes out.
3. Microsoft gets tired of sony outselling them and purchases Square-Enix (Final Fantasy, Dragon Quest, Kingdom Hearts) and Electronic Arts (Fifa, Madden, Mass Effect, Battlefield, Star Wars) effectively ending the console wars.
4. The Nintendo NX amazes everyone and goes on to sell 200 millions units in 10 years.
