Ok after catching up on everything here, since ive been away a little but..
First off, I just think I WANT the show to be canon and it SHOULD BE because if it weren't, then the kids would be confused of the time line when they discover and watch TLK 1 and 2. Besides, If I'm correct, after lionesses had there cubs and the cubs grow up to adulthood, they can have more offspring again even when there other sons and daughters have grown up, don't lion cubs have big sisters or brothers too?
Also there is nothing wrong with Kions look or colors he has all the same features of the rest of the TLK lions, ans the coloration is not out of the TLK color pallet code, and I would know I am an expert on all there features considering im a old TLK artist that loves to draw and color them ALOT So I studied all those features perfectly. So it is safe to say they did very well with Kions look, he look VERY 100% TLK. Mufasa had a bright red mane and so does our Simba

and that's the color of Kions. and what wrong with his Mohawk? its cute, How else to males get there manes. Kovu had one brushing down his forehead

. Whats wrong with Kions Mohawk brushing toward is back? and I will say when I first looked at those pictures of Kion, I have to say I was not happy about them at first because I thought they made him look like Elvis Presley

and I'm no fan of him, no way I hate his music, and I dont like his look no offense to any Elvis lovers out there. but I realized in the animation that's not the case. So Kion is pure TLK material just like his family.
Last but not least

PLEASE PLEASE PLEASE Dont bring up the thought of them canceling it, DON'T JINX IT PLEASE!, just prey to your god that it will be good and not as bad as we may think. Seriously I cant imagine life now without a new Era in TLK now. I just cant anymore and I don't want to live without one ever again as a TLK fan. I will be devastated if they just don't continue with it.
