After a fair amount of speculation, the ever-patient and super-stretchy Dhalsim was officially announced for Street Fighter at Paris Games Week.
His play style is built around keeping the opponent away and being able to strike from long distances. In a new twist, the most obvious change to his projectile moves is that they now can travel in an arc, so it might still hit an opponent that you thought was going to jump in even when they're on the ground.
Here's some examples in gameplay from some Canada Cup players.

Some data for other characters has been found in the data files contained in the latest beta versions of the game. If you have a look at this image, this is some raw code from the beta that had been picked through with a hex editor, looking for file names similar to the structure of the files in Street Fighter 4. Only time will tell if this really true or not, because they're still working on the game and parts could still be changed at this point.
Bonus tip: Angry Birds 2 - complete a section of a level with a single bird, and you get a "Strike" - they're 25,000 points. Complete it with two birds and you get 10,000 points. You don't get any direct bonuses for having birds left over at the end, but if you gets lots of strikes and birdies, you probably will have birds left over.
