That is merely gossip, i've seen no factual evidence that supports that. Here is something to consider: 1) Hitherto Amiga has developed their GUI using the neutrino microkernel, it is reasonable to conclude that all their work on their GUI has been outside the kernel. 2) If Amiga included the GUI in the kernel, I believe they would have to release the source code to it, correct me if i am wrong. I do not believe they would ever release the source for their GUI, it would be a horrible business move.
