At this point I'm sure denjiro is kyoshiro. but why the he** did oda tell anime guys
It's more confirmed now because denjiro being kuoshirou has massive inconsistency.
As per VC, kuoshirou home town is east blue and not wano.
So, if he was born in East Blue then for him to be denjiro, we have to assume that he migrated to Wano at very young age and grew up with rest of the scabbards and gain oden loyalty and even participated against Kaido invasion.
But kuina present age would be 22 years old - born two years before Kaido invasion in wano.
However, VC states kuina home town to be shimotsuki village. This is bringing inconsistency in denjiro being kuoshirou. However, there could be some twist involved here but as of now numbers aren't adding up in this theory favor or I am overlooking something here
