I have to say I agree for the most part. Neither the Royal Starship or the MTT excite me all that much either. I used to always regret having to pass on the Queen's ship at TRU years ago (when it was on clearance), but at this point I really don't have room for a lot of big stuff (and it seems like we're starting to get more and more of it) - and any room I do have I'd sooner save for something better than these.
I think it would be a mistake to make anything too terribly high dollar from TPM as well. They would be better off BMF-ing more OT ships, or tackling something else spiffy from the Clone Wars era. I think those are the two things that can push items of that size at retail, but I guess you never know. I'm fine with them recognizing the 10th Anniversary of TPM (although I'm guessing a lot of fans would be "meh"), but if they wanted to do a 10 figure line or something (for the 10th ann.) with "ultimate" versions of the biggest characters from that movie (Obi-Wan, Qui-Gon, Padme, Jar Jar, Anakin, Maul, etc.) that would be fine. Also, even though I have one, I'm always a little surprised we haven't seen the Naboo starfighter re-released in the starfighter line as well. Again, that shows how far away Hasbro has stayed from TPM stuff, so investing in something large and pricey seems kind of surprising to me as well.
