Not too soon, I'm afraid. Our review unit is decentered and currently on its third trip to Sigma Service in Germany. See also this thread:

Very close to the Nikon 70-200 VR II.
Max. Magnification at MFD of 70-200 VR II: 1:8.33
Max. Magnification at MFD of 70-200 OS: 1:8

Markus is of course right, but has to mention the MFD for both lenses too, because if the MFD would be very different, the same magnification factor would not indicate the same focus breathing.
The Sigma OS version has a Minimum Focus Distance of 1.4m, the Nikon VR II has an MFD of 1.4m also.
So yes, both lenses are very heavy breathers, and the exception in the 70/80-200mm group.
Compared to:
Nikon 80-200mm f2.8 D: MFD 1.5m, max. mag. 1:5.9
Sigma 70-200mm EX DG HSM Macro II: MFD 1m, max. mag. 1:3.57
Tamron 70-200mm f2.8: MFD 0.95m, max. mag. 1:3.1
Sony 70-200mm f2.8 SSM G: MFD 1.2m, max. mag. 1:5
Pentax 80-200mm f2.8: MFD 1.4m, max. mag. 1:5
Canon 70-200mm f2.8 IS USM II: MFD 1.2m, max. mag. 1:4.76
So if you, like me, want close focusing ability with a narrow field of view close to 200mm, you best look for other options than the current Nikon and Sigma "portrait tele zooms". For others, this focus breathing might be less of an issue.
