Having seen Paladin's Sona myself, I would agree.
You know what else I've seen? The patch notes!
4.10 brings a boatload of champ changes and item changes and whatnot, but for those too lazy to look at the site, I'll see what I can do.
Skins
The following skins go on sale this patch, for 750 RP unless otherwise stated:
Goalkeeper Maokai
Red Card Twisted Fate
Striker Lucian
Superfan Gragas
Sweeper Alistar
Primetime Draven (975 RP)
Champions - Reworks
Nidalee was one of two reworked champions this patch.
Skarner...well, it's not a rework, but a refurbishing of the last one. He gets a new passive, along with some other changes.
Champions - General
Diana's Lunar Rush no longer procs her passive.
Galio now gains Magic Resist per level.
Gragas now gains the damage reduction from Drunken Rage regardless of whether it's interrupted.
Karthus now has an eagle join in his dance. (Statue of Karthus skin only)
LeBlanc's Sigil of Silence Malice no longer silences.
Lucian received a tiny nerf, that being to the AD ratio of his Ardent Blaze.
Pantheon can no longer cast summoner spells while airborne.
Sivir's base mana, mana per level and mana regen per level were all buffed.
Skarner got a Texture Update!
Tristana's Rocket Jump mana cost has been reduced. In addition, her Buster Shot range matches her autoattack range.
Twitch's base AD, passive, and Ambush, all nerfed.
Champions - Insignificant Stuff
Bug fixes or other small changes were made to the following champions:
Gragas
Karthus

Items - Attack Speed
Dagger saw an increase in Attack Speed and price in the shop. This has adversely affected other items as well. Check out the notes for more details.

Randuin's Omen no longer slows attackers.
Frozen Heart is unaffected by these changes.

You may now only duo with friends in the same tier, or one tier above or below you.
Team Builder
Captains in Team Builder will now be able to see a list of "Suggested Players" that they are able to invite into their games.
That's it!
I've had the pleasure of trying out these "new" items, and this is, in case you couldn't tell, a massive buff to AD carries (sorry bruisers, but get rekt); each one benefits from a different life steal item. Ardent Censer also helps too for those Attack Speed heavy carries like Twitch and Vayne. It'll be a good patch for Vayne, that's for sure...
EDIT @06/29: Diana was nerfed in this patch and it went undocumented, I've added details.
