Nah, there'll always be talented 2D animators around, even of that calibre. Problem is that there's no opportunity for them to work in 2D no matter the talent, so they probably don't bother to master their skills.
i know a bunch of folks that work with ToonBoom professionally, and they're generally pretty bummed out about it - because even tho it's faster, more efficient and in demand, they miss to
draw. What joy is it to animate in 2D an not drawing?
With that I mean to say that there isn't necessary a problem with animators not wanting to hone their drawing skills, but it isn't what studios want to invest in. Which is a fucking shame.
I would kill to see Kung Fu Panda animated in 2D, especially because of Nico Marlet's fantastic character designs!
