Its possible, but not gonna happen by the end of this year. Actually, if sales trends continue, they basically should happen around the same time.
If the PS4/XB1 keep selling at the same ratio and those sales translate to holiday boosts, for one to reach their milestone will mean the other has already reached it or is just a week or two away from it.
2015 will be a much bigger year for sony than this year though as FF15, Persona 5 and MGS5:PP which are all basically exclusives for sony in japan will jump start that market. Coupled with an inevitable price drop I predict sales in japan alone topping at around 4M for next year alone.
