After a "teaser" trailer earlier in the week the folks at GW have now added the paints to their website for release later today. The website also shows a dead link to some painting guides for different armies. Presumably as a way of showing you how the new paints will fit in with your previously painted models.
There's a "mega paint set" of sorts for a whopping £333 which includes a army case to store them all in. Now I know they'll sell and I was fully intending to get one but for that price I simply can't justify it.
