We are waiting for Project Talon for a loooong time. It'd be awesome if it was a legendary
for sure
Syndra. There's so much potential (pun intended). Especially with Coven.
if it doesn't happen this year i don't think it ever will
Ivern or Maokai. Shen is cool too.
pls pls pls 

Well, not this year specifically, but I would love to see
get a legendary (or ultimate) skin one day. Yes, all of these are some of my top played champs (beside Amumu because I don't jungle)
If Morde gets a legendary skin, then he wont get a vgu anytime soon, which he desperately needs more than a 3250 skin.
SYNDRA
Personally:

Incredibly unlikely though. Warwick has very small and short range particles not very suited to a legendary skin. Wukong is a bit better but until we see a VGU I doubt that even close to a possibility since his player base is so small. Ekko is the best chance for my champion pool as he has a lot of pretty and long range aoe effects but I don't think he has the player base dedicated to justify that kind of skin.

Anyone but
.
I have made up my mind to never spend money on this game again, and Hecarim as my main would make it hard for me to resist.

Still hopeful she gets one.
Make Trundle Troll Again!
I'd like to see some lore-related legendary skins. I'm not sure who would be the best candidate, but some sort of "what if" skin or a "past version" skin. Blackfrost Anivia sort of falls into this category, and its really cool (no pun intended).
I know Kayn recently received a legendary, but some skin for him that shows a theoretical future where he and Rhaast cooperate instead of defeat one another would be neat. More recently, I got the idea for some "Past Morgana" skin, where she hasn't bound her wings yet and still looks more similar to Kayle. Maybe a "Dark Kayle" skin to pair with it, where she ends up looking more like Morgana.
along with skarner, he's the champion that's waiting the most time for a skin, nearly 4 years. He got no balance changes underway, he's not problematic. Dark Star would definitely be the most fitting theme right now, especially since there are some very cool concepts around!
There are some good suggestions here. I’ll go with Quinn. Xayah and Rakan would be awesome too but I think there are other champs more deserving at the moment.

are assured for a legendary or even this years' ultimate. Jhin has the highest playrate and Zed is at #7 and they've never got a significant skin like that.
What I would like though?
