Not to mention Devil Jin's laser that's been around for longer than that. There are also at least two characters that have had bad breath that you could use, though it didn't have much range ...
Could be about the initial issues with online. I don't know if they were specific to the PS3 version, but they've been patched out and the online code performs fairly much like the SFIV's does.
Was just watching these high-level competition rematches. Tekken 6 again holds up really well at tournament level. The new Lars character looks quite powerful too ... Very impressive Lee play by the way, never saw him much as a high level character.
