Because of the "credit crunch" that has precipitated the whole economic slowdown around the world, If someone wants to buy them they will probably have to pay in cash or have an enormous amount of brownie points stored up with some bank. Given the number of publishers who have official, or unofficial buying freezes, this probably makes for a very short list. Either way, this likely means either a major change, or extinction of a brand that is entertaining, and well run.
Given the well documented layoffs, and reorganizations of major publishers, i can't see anyone who has an SF/F imprint taking on Solaris and doing the right thing by making it mostly or completely autonomous. It's just not enough a part of human nature for someone to make a purchase that large and then leave it alone. Either favors will be called in, or some bean counter will wish for a more profitable editorial team (read less expensive) or they will decide to move the imprint to the US or Germany, or Russia or wherever and lose people that way. On a small team that already lost a key person to Angry Robot recently, those one or two people lost could have a huge impact on the product.
Who knows, maybe I'll be pleasantly surprised and someone will buy them and take a hands off approach, or Games Workshop will decide that as good as the goose might taste the eggs are a nicer thing to have overall. Either way I wish the Solaris team, and their authors good luck wherever the land.
