I've done a bit of research and as far as I can tell there won't be an LBA3!

The game was meant to be made by Adeline Software, who made the first two. They became NoCliche and were then bought by Sega to make Dreamcast games. They did work on a basic design for LBA3. "Genesis of the stellar entity" was the working title but as far as I can tell nothing was ever made. Adeline and NoCliche now appear to have disappeared completely!

So I guess the answer is no! There won't be a sequel!
