There are so many variables that make it difficult to predict although I do think the recent news that it will miss Christmas and move to March 2017 for its launch is very negative. Personally I find March I'm still paying off Christmas and for purchases in the January sales and have a huge glut of games to play that I have received at Christmas. I also find March a busy working time historically where I'm building up holiday for the summer and have little leisure time. Parents buy consoles for children at Christmas not March so many people interested won't be able to get one through lack of money. The end result could be a weak March launch rather than a stellar Christmas launch and this does huge damage.
If the NX launches underpowered compared to Playstation Neo at similar or higher cost I think it could achieve less sales than wii u.
