It seems that there is far more interest in the minifigs themselves. Personally, I'm far more interested in a minifig pack. Its been years since we've had a good source of 'castle' minifigs. And this theme, more than any other seems driven by minifigs. LEGO has seen fit to release the community workers minifig packs for the City/Town line. Why not do the same with some of the more popular castle minifigs? A few Knights, soldiers, forestmen, peasants etc. would be invaluable to newer castle fans looking to build their armies.
Older parts could also be offered in newer colours to freshen things up (dark red hoods for example). Look, I liked the Legends line for what it was, but I think that there are greater possibilities out there for the classic-castle fan. I'm uncomfortable pushing for the return of the Legends line when something greater could be running through the pipelines at LEGO.
So do people really want the old sets, or are they simply yearning for a classic-look to return? Still, this poll is quite interesting.
