How about he takes it up to the next level! Goku is the Super Saiyan God, a power beyond that of the Super Saiyan 3! He has red hair, red eyes, and what looks to be an even more sparkly gold aura. The Super Saiyan God pictures, or rather scans, come from the latest issue of V-Jump. There is also an interview with Akira Toriyama. Translation coming soon to this post.

p.s I dont have a problem with the god look but either way we dont see a clear picture of it and could just be the start for all we know
We've got a close-cropped shot of his face, revealing red eyes and red hair--that seems to be tinged gold at the tips--going up like in normal SSJ form... and another pick of Goku, also close-cropped, with red eyes and red hair in his normal style.
Waaaay too soon to judge. It would certainly fit if the "god" for was more "normal" that the increasingly bestial SSJ3 and SSJ4 forms... Toriyama has always had that theme going--increasingly powerful forms get bigger and uglier, but the final form is always small, compact and simple. See Frieza, Cell, USSJ, Buu, Gohan, etc.
I hate to say it (I really do), but Toriyama should have stayed retired. He is completely destoying the best part of my childhood by selling out Z.
Regardless I just hope funimation gets this very soon.
Piccolo's Fusions with Nail/Kami - no visual change
Frieza's Final Form - smaller and simplified
Cell's Final Form - dignified and streamlined
Gohan's Mystic Form - no visual change
Sometimes taking simplified approach is a good thing. Otherwise the same idea can keep going in the same direction and eventually lead to...well...this. --> http://i32.photobucket.com/...
This is actually something I would expect Akira Toriyama would do. Make something that's familiar, without it looking like fan fiction you see everywhere on the internet.
Akira comes back to pen a movie that's canon to DBZ 20 years after he closes out the series, this is awesome.
