The Merril camera alternative

I'm wondering if there is indeed a 'connection' between Sigma Merrill and NEX E mount.

The DP1 has a 19mm lens, The DP2 has a 30mm lens, both for APSC, The Sigma E mounts and MFT are 19 and 30mm, I wonder if some shared development went on here. The 30mm version seems to be the most highly acclaimed.
