The Necrons getting shoved back, possibly even way back seems a little far fetched, however its out roaming the blog-o-sphere today so here it is. The others add a grain of salt to, since as we get closer the rumors should be getting a little more accurate. Here are the rurmors, Grey Knights first, Necrons a little further down.

Necron Rumor via Spectral Dragon on Warseer
After an email or two I have heard from a good source that Necrons might get pushed back to next year.
The story (that I have heard) is that they are having a VERY tough time with the Necron Fluff (the army entries and models themselves are mostly going smoothly, according to my source.) There are a few core things they need to change and apparently Mat Ward is having a tough time with it, so several people are now on the project.
They also are not entirely sure the direction forward they want to take with the Necrons, apparently. So the army might get pushed back to 2012. If they suddenly come up with some inspiration then it might only get pushed back one slot.
This makes me a very sad Kill-bot.
