The true sign of a master is when you’re able to impress everyone with your execution of a skill that might otherwise be considered mundane. So it’s probably quite safe to say that in order to dazzle anyone with your skillful shoveling, you’re going to have to be rather good at it.
With this in mind, allow me to introduce Yorick, the Gravedigger. In addition to being more adept in the art of entombment than any who have come before him, he makes a point of keeping good company… or at least ravenous undead company. One of those two.
Special Note: We’ll be behind closed doors at E3 showing off a few of our upcoming champions, including Yorick and his host of undead friends. But don’t worry: Everything we’re showing at E3, we’re reproducing here on the League of Legends website! Stay tuned for more details during E3.

Here is a bit of clarification about the release time frame for Yorick. It has already been mentioned by reds that the champion following Orianna would be on a three week cycle to accomidate for Dreamhack, so no surprises here.
Summoners!
The end of Season One is approaching fast, and between the Season One Championship at DreamHack and E3, there’s an awful lot to do here at the Riot Office. Additionally, Orianna was an extremely exciting and edgy new champion, and we want to take the extra time to ensure that the next champion will be just as groundbreaking before we turn them loose on the Field of Justice. For these reasons, we’ve decided to take a bit of break from champion releases and balance changes until after we return from Sweden following the Season One Championship.
As we draw closer to these events we will be releasing more previews of the exciting content that will be coming sometime after our end of season break. This will include Yorick, the Gravedigger and several more champions along with some exciting new features for PvP.net. Stay tuned for more information as our coverage of E3 continues.

As with the mention of a few goodies in light of E3, I can't wait to see what they have in store for us. I think I speak for most of us when I cry out "MAGMA CHAMBER, PLEASE!"
