It certainly is an interesting idea and it would be a good way to bring Sakura back into an important position.
But I always assumed it was just a simplified or abstract version of the seal on Naruto's stomach. A spiral to show that Kurama was still under Naruto's control and it open to show that Naruto and Kurama are now allies. I believe its the same symbols as when Minato fixed Naruto's seal in the Invasion of Pain.
I dunno where you guys are taking this but i mean, look, compare sakuras symbol on the left to narutos symbol on the left its EXACTLY the same and theres no denying that, any objections?

@dovahkiin 1st i already agreed on that

and 2nd im not talking about the one on his stomach im talking abouy the one on his back.@james S cassidy, yeah kishi is but what do you think about the mark on narutos bijuu transformation?
