Difference between Wii and Xbox One is three fold (imo and from the little I know):
1. The Wii had a low price point. Now, I know that the X1 hasn't had it price revealed yet but with the things we know about its specs and the fact that it will likely come with the Kinect 2, its hard to believe it will be less that 400$
2. The Wii had Nintendo games. This seems like an obvious point but I'd say there was a fairly large amount of gamers who bought the Wii solely for Nintendo games. The X1 doesn't have this luxury as the Xbox exclusives aren't as big system sellers as Nintendo exclusives. It is hard to believe that someone would buy the console solely for the exclusives (although it will likely happen with a relatively small devoted following).
3. The X1 will likely have 3rd party support. This pretty much puts it as a direct competitor to PS4. Will gamers/non gamers buy a console with 1st and 3rd party games or a console with 3rd party games and misc services? That is yet to be seen...
Basically what I'm saying is that the X1 has positioned itself in an interesting place hoping that services will out-compete Sony's exclusives which is a very different place than where the Wii was which was a cheap and accessible game player. Because of this is expands into the literal non-gaming market and could potentially sell as a TV buddy instead of a games console and I could see it being purchased and never gamed with by some.
DISCLAIMER: I do not know everything about the Xbox One, its future, its games or its competition's games. I am only basing this off the information I know and I believe I can logically assume. Regardless, feel free to contest my points, I'd love to hear the counter points.
