I heard somewhere, can't remember unfortunately where it was though (sorry), that Utapau is where Grievous and Kenobi fight, and there's something to do with the duel being on top of something where you can see the grand landscape of a huge area of Utapau, so I'm guessing on top of a hill or valley of some sort..but I don't know about the terrain of Utapau.

EP3: Planet Name Revealed?

Sompeetalay from TK-421 makes this small observation:
If you check out the new daily Hyperspace comic, you'll learn the existance of a planet called Felucia. If you remember well, Amy Allen herself claimed that Aayla Secura would be on a planet starting with the letter 'F' in 'ROTS'. Could Felucia be that planet?
Could be, who knows ...
