I'm sorry to anyone that likes his model, but it's hideous. I see Urgot and Eve getting VGU's which I support because their models are pretty old, and I suppose both need it for the gameplay aspect too. Nunu looks absolutely terrible though. Will he be getting help soon?
is most likely the next candidate to get a new base VO along the release of her Legendary skin, Pulsefire Caitlyn (which was leaked some time ago, along the leaks of Xayah and Rakan, and numerous other skins and Champion Update information).
Since 
voice actor was recording Elementalist Lux at the time, she was also asked to voice some new lines for Lux while she was there. It is safe to assume they will do the same for Caitlyn if they use the situation to get her voice actress to do the lines while she is there to record the lines for the Cait skin.
Nunu is on the list for the VGUs and he is even among the Tier1-candidates. However there are more than 10 champs among the top candidates,so we don't know if he might not even make it before 2019
he's not the only one
Who cares it's FUCKING NUNU!!!!!
I'd say he is likely in the batch after Urgot and Eve.
