This prePub is about a mi=onth old but appears to have stalled since the first week or two:

I came across on Amazon today an 11 volume collection (due for release in September by the same publisher, T&T Clark, as the Logos version):

It looks to me like both sets have mostly the same material.
Even after a 37% discount from Amazon, the Logos version (at teh current PrePub price) costs less than half of the hardbound version.
