Not a success because it didn't come close to XB 360 unit sales. Software aside, XB1 needed to get much closer to XB 360 hardware to be considered successful based on their future roadmap for that gen.
Not a complete failure either. Somewhat similar to the PS3, XB1 made a reasonable comeback, though screwed themselves much worse early on.
XB1 and PS3 were pothole consoles. A deep bump in the road that required an on the spot tire change, asap.
Beware of the curse of the 3rd gen they say...
PS1 - ! - We must build a console that can alert our enemies.
PS2 - @- We must build a console that offers online living room gaming.
PS3 - #- We must build a console that’s powerful, social, costs and does everything.
PS4 - $- We must build a console that’s affordable, charges for services, and pumps out exclusives.
PRO -%-We must build a console that's VR ready, checkerboard upscales, and sells but a fraction of the money printer.
PS5 - ^ -We must build a console that’s a generational cross product, with RT lighting, and price hiking.
PRO -&- We must build a console that Super Res upscales and continues the cost increases.
