I'd say the best thing about these is that by creating the UGH, Hasbro has admitted that the line (during non-movie years) is aimed at collectors. This is good because whenever Hasbro does a Q&A they say the line is aimed at kids, next time they do this we can respond by pointing to this sub-line and proving them wrong.
I'm no Hasbro basher, but they do get a bit defensive when the do public appearances.
They can and will still claim that the line is geared towards kids. Pointing at the wide variety of lines that are primarily for kids: Galactic Heroes, Force Battlers, Transformers, Attacktix, etc...
They can also make a claim that the regular 3.75" figure line are not for kids. What the UGH, VTSC & Titanium Lines do is allow them to simply say "see we're offering things for you collectors too".
There's a show I like to watch when I get home in time called "Attack of the Show" on G4 - back in February they covered Toy Fair. Now you would expect that the audience for this show would be primarily toy collectors, not kids. Well, when it came time to cover Hasbro, there was Darryl De[Retarded]Priest gushing about the "all metal" figures which are "new".
So that's my point, you corner them at a con or some other event and they will simply hold up the Titanium Figures and say "but we made these for you, collectors!" and then when the line fails (which it will if the amount of the first wave collecting dust locally here in NJ is any indication) they will point the blame at collectors and say "well, we gave collectors a chance and they didn't support the line, so that's why we have to gear Star Wars to kids, blah blah blah"
