PS4, just because of the support for it already, and i say Xbox 720 will lose because of the fact that Xbox's rumours actually become true. Banning of 2nd hand games, will cost it big time.
Also, i expect a tie between the 2 in the USA and UK. Price will determine everything though
Xbox Series, PS5 and Switch (+ Many Retro Consoles)

Prediction: Switch 2 will outsell the PS5 by 2030
