I think that with 
they set their minds on keeping it a mystery weather he's a yordle or a human, in spite of that, he also has both yordle and human characteristics, for example: 4 digits instead of 5 and no ears whatsoever... that said, I don't think they'll move him into yordle territory much (adding ears would be a big no-no). Still Amumu NEEDS a VU badly, though more focused towards the fact that he's a mummy instead of a yordle like his bandages could float around as he moves and he could look way more sad than he does now, also his feet need to be defined, he's a mummy who wears boots??? he needs to be barefoot (with bandages) and this could either be yordle-like or human-like.
has always suffered from pumpkin head just like poppy, so yeah she'll need some sort of update... also, even though she's kind of new, her body doesn't look like it has much anatomy, at least in the chest area she's really really thin so perhaps giving her a bit of volume would be good, not like MF sized boobs but at least a ribcage ._.
I can't wait for him honestly, I think that Kennen is an AMAZING opportunity to create something really cool, he's feral like a yordle and composed as a ninja I only hope they uncover his head a tad and move away from the Rantarou reference a bit xD though he needs heavy bug cleaning and perhaps an update to his ult mechanics so I wouldn't expect his VU this year =/...
Last but not least, Sata... Teemo xD I can't help but wonder about the new VO they'd add on Teemo, currently we get so much information on champions from their VOs and getting to know Satan is... well... scary xD though Teemo being the main face of the Yordle race (the Superman if you will) they'll probably take their time to get it right. Also with Trist's new body I wonder if they'll remove Teemo's belly a little bit, not like giving him a six-pack or anything but making him less pudgy would be more in line with him being an almost military force. They'll definitely keep the hat (so much merchandising around this feature) and the color palette, perhaps adding a vest and getting rid of the necklace and boots altogether.
the corkster!!! I love this guy and his moustaches u.u wish mine would reach such heights and float around instead of flop down xD... He needs love as well and I can't wait for them to make him all fluffy instead of an old geezer... but I can't help but flinch at the idea of Corki being more human than yordle in Riot's eyes =/ in his concepts he wasn't thought to be a yordle at all but this version of Dr. eggman that scares the bejeezus out of me... I pray, PRAY!!! they move away completely from that and enter full yordle territory, keep the whole airforce lingo on, but full yordle please!
is amazing. She has a lot more anatomy than her predecessors. She far outshines even some of the newer Yordles. 
looks almost outdated next to her! What is the VU team's thoughts about the rest of the Yordles? Whom of them are slotted for a similar scope update?
Is of course on her way. Will 
's childlike anatomy? Whom of the Yordles only needs smaller tweaks, like model-swaps? Will *any * future VU's for the Yordles be smaller in scope than
