Can't agree here. There's simply no other droid known as "destroyer" in the entire SW lore than the droideka (Insider's Guide, EP I Visual Dictionary etc.). If you know of some other destroyer droids that are not also known as droideka please let me know it.Anguirus wrote:"Destroyer" sounds like a general type/goal to me, "Droideka" would be the specific model. This is backed up by literature IIRC (such as Survivor's Quest).
The usage is also correct in the film: Obi-Wan just recognizes them as destroyer droids, while the businessmen who purchased them know the brand name. The point is, if this is only valid for a translation of the film I don't think it can be construed to help your argument...not that IMO it did much in the first place.
The characters aren't supposed to be speaking any earth language so I'd consider both "translations" to be equally valid. The only unusual thing Obi Wan notices about these particular destroyers are their deployable shields, so we can presume he's at least somewhat familiar with the product line. The final battle does feature shieldless droidekas after all.
For everyone else, Qui Gon's words are "It's a standoff, let's go" before they scram, which I think doesn't seem to indicate that time is the factor here but the inability of the two Jedi to depose of the droidekas.
In the original script the two were supposed to be attacked by a dozen or so droidekas from all sides, which would have made their hasty escape way more plausible.
