Sp4 4g lte

[JMV83]

Hey anyone has any news on the 4g version of the new SP4.

Is it still coming out this year?

Any educated guess as to when?
Compared to their usual product cycle when would it make sens to launch it?

I'm hesitating between an SP4 with 4g and a surface book...the 4g would make the difference

Thx y'all

I guess it's a very well kept secret IFA 2017 maybe???
