It is kind of hard to figure out how much X1 has shipped, but my reasoning is this:
We know the combined shipments for X1+X360, and separate shipments for the first two quarters when they were on the market. We can also safely assume that X1´s part of total shipments will increase as time goes by, but I have been a bit moderate with the relative growth. Here are my approximations on X1´s part of total shipments based of the first to quarters that we know of. Considering X1 had a very succesful december, I believe 360 fell even more, but I have calculated with a 70:30 ratio for simplicity. this would put X1 shipments at 12mn by dec31st.

It is therefore pretty safe to assume it stand at atleast 11mn sold by Dec31st.
