PS4 - 147k
WiiU - 35k
X1 - 65k
These are not baselines, this is the lowest I think each console will dip for 2015. Ps4 will have an extremely strong year due to being relevant in nearly all markets, along with the Chinese launch during their holidays. I only expect sales to dip to 147k during summer, and I'm being pessimistic with this prediction.
With a performance disadvantage and lack of major exclusive IP until presumably Q3, there isnt much reason beyond friends to buy an x1 for most of the year. I see sales dropping quick after Christmas with an overall dip down to 65k, possibly more than once. I'm considering this an optimistic prediction.
WiiU is hard. Despite everything though Nintendo has had trouble spurring sales. I think baseline might be close to 50k with a drop to 35k once or twice and many small upward trends as new games role out. For all we know the baseline could steadily climb all year. I expect Amiibo to do well.
