Games Workshop Paint Change

We are looking at some form of change to the Games Workshop paint line later this year.  No idea what the company plans on changing, whether it's a new formulation, new sizes, a shake out of the color line or what.  We have just been told that, due to the change coming , Games Workshop has told us to keep inventories low and are allowing stores to buy bottles in single quantities instead of in sleeves of six as is the past.
So, if you are a fan of either the current color line or formulation, you might want to stock up. conversely, you may want to let your paint stocks thin out, in anticipation of whatever happens.  Unfortunately, we don't even have an idea regarding when it will happen, just sometime this year.
