[quote="juhouh"]TLG is as canon as Timon and Pumbaa spin-off series which both seems to be a bit off from the original story line. If TLG characters are canon then Smolder the Bear, Quint and Cheetato and Cheetata are just as canon too
TLK and TLG are different but both from same company[/quote]
Usually spinoffs aren't direct continuations (assuming disney doesn't do something stupid like retconning almost everything about sp)
I always viewed tlk1.5 and the timon and pumbaa show as 'what if's' similar to the elseworlds comics at dc.
I will concede that it isn't canon IF It isn't a direct continuation of tlk2 or if they retcon the heck out of it. And kovu hasn't been confirmed to not be in it no matter what that mtv article says about kovu being dead. not even the actress for kiara or the writers of the show can legally say if kovu is in or not (i should know, I tweeted one of them).
Considering that don hahn, the producer of the first film endorsed it at D23 just a week and a half ago points towards me being right but who knows, I might be wrong.
