Not sure if everybody here has been too keen, however I'll post the info just in case.

Two new teaser trailers have been posted in the marketplace which give us a little more flash into real-time gameplay. I'm sure they've been copied and pasted all over the interwebs by now...but in summary:

We know for sure that Raph, Siggy, Nighty, Mitsu, Taki, Tira, Asty, Ivy, Zas, Cass and Sophitia all make the return (just from memory). The new Asty character model looks absolutley lethal.

Seems that semi-destructible backgrounds have returned (ala SC3), with one scene showing Asty punching somebody into a wall that shatters behind them (leaving room for the RO).

The gameplay was fast and fluid. The jump in speed is a little larger than the jump from SC2 to SC3. Weapon trails were pleasingly bright and colorful. Animation already looked super-smooth and polished. In fact, the character models and textures themselves seemed a little TOO bright in the light. The high-white value of the sun reflecting off everything almost takes away from the devastatingly detailed character models. Take a gander for yourself...see if you agree.

Still, everything looked breathtaking. Nighty and Asty's costumes are to-die-for-awesome. The detail on Siggy's outfit and his Calibur are...well....amazing. The voice acting (which may just be placeholder for now) was not too-too bad....a little more convincing than some of Cassie's lines from SC3 ("Winning is all that matters...winning").

The mysterious new female character wields a spear with some moves taken from the custom Calibur character in SC3, and a wee bit of Kilik-ish moves (with no sign of Kilik yet, does that mean that he's out)...but she also brandishes a sword on her side that's stylish to Cervy's secondary sword.

Anybody else have any criticisms or things that they've noticed?

nope. Seems you hit every nail on the head.
I just hope Kilik made the cut. He's my favorite character and i've used him since the first SC. If he's gone i guess i'll use Nighty more. Oh well. Oh and another thing, my sister is badgering me about a Wii release for this game. Anyone hear of anything like this?
