So based on a hint I received on a comment in this forum earlier this year, I believe this set of two guns may be accompanied by a sister set with two limbers with crews in the future. If I am correct in this assertion, then the idea would be that between the two sets you would end up with two guns, two limbers, and crews for all between them.

Naturally it is up to personal preference, but I would actually prefer this to Zvezda's GNW way because each would have a limber to tow the gun. I also vastly prefer the plastic that Strelets is made out of, so looking forward to the final results!
