I'd guess that Brunswick will be "cleaning up" their line-up. Getting rid of the Sieges as ball lines makes IMO sense, since it is hard for customers to see a true difference to the C-System line.
I'd guess that the C-Systems will live on as high end ball line (with a replacement name becoming due to the end of the year, I'd say), and that the Revolvers' line will become a symetrical core performance line under it, above the mid-price segment, maybe with a new introduction and ball line name. Timing for that would be O.K., too.
And, maybe, a Urethane and a mild reactive Karma, just in order to get rid of the leftover Avalanches?
