Source? Because here we only see SkyFan91's testimony...
Anyway, VV openly saying they hate "the competition" (Traveller's Tale at the time)... sounds absurdly uprofessional and thus hard to believe to me, to be honest.
Anyway, as far as we know, some staff from TfB are the ones that might be behind the Spyro remake right now, not VV (do you remember that "super secret" project on Unreal 4?).
I do remember it.
Though, Unreal Engine 4 for Spyro's remakes...?
I don't know, wouldn't want them to end up looking like some fans' projects on YouTube, and loosing the cartoony style.
Crash's engine would be perfect for them (Alchemy, right?).
Did they openly say that...?
One thing is disliking the games, but hating other developers who worked on the same series...?
Nah, I highly doubt it.
Anyway, here is the link to the source:

Haven't seen the stream myself (Odyssey is holding me hostage, lately) but I'm confident this forum is a pretty reliable place.
