I'm not really sure, but I think it will follow the normal borland pattern, which is standard (The basics), professional (Database access) and enterprise (Client server 3 tier)...
The standard level of JBuilder and C++ builder (On windows) has been released for free (I think) so it's resonable to assume that the basic Linux version will be either free, or just cheap.
However, it's possible they will give away the compiler, and try to get you to buy the Environment bits... =)

All should be clear by the end of the year (when it should be out... =)
