Just habitually looking at the PrePub resources sorted by ship date, I found at the bottom of the page that a new volume of the SIL Exegetical Summaries series is about to ship in less than two weeks!
It covers the first half of the gopsel of Mark: http://www.logos.com/product/29521/an-exegetical-summary-of-mark-1-8 - the product page for whatever reason doesn't contain the box "want more of this series?" with a link to the 24 vol. series (which has two volumes on Luke and one on the Sermon of the Mount so far in terms of Gospel material - all of them available individually) or the recent two-volume update.
As I find these to be very valuable in researching contested translations and explanations, at nearly 30% off the new volume was an immediate quick-buy for me!
