There is a summary of known Tyranid rules that have now been revealed, although still hold some room for error, as we have not yet seen the codex. So check them out, and here is a first look at the rules we will be seeing in the upcoming codex.
Please remember that these are still considered rumors, until we start getting information right from the codex.
