I sort of divide them into 3 distinct phases:
1) For the early history of Legoland (~1984-1992), the idea seemed to be that factions were evergreen. New sets would be added to each faction each year, and some factions were phased out in the interim. In Space, factions didn't so much exist, but the color schemes from year to year differentiated "styles" of the single all-encompassing "classic" space.
2) For most of the 1990's (~1993-1997), a single new faction was introduced each year, and few (if any) subsequent sets in that faction were released. Things like Dragon Masters, Royal Knights, M:Tron, Islanders, etc, were all released in a single swoop, in 1 year.
3) In the very late 1990's through today, factions were/are released in groups, to be their own microcosm rather than a subset of a larger theme. So you get things like "Kingdoms" which is actually made up of two factions: Green Dragons and Red Lions. Or you get "Life on Mars", which was made up of Humans and Martians. The concept of an over-arching theme is lost, and themes instead are focus on their own particular visions.
I think for us adult fans, we typically like the #1 or #2 approaches-- we want an over-arching theme that will last for years... Because we plan on being fans for many years! But for kids, I think #3 makes more sense, as trends come and go quickly, and kids generally have the same appreciation for the long haul as adult fans. As such, I expect we'll keep seeing this type of release structure-- themes released in pairs to facilitate conflict, at the same time making them constantly "New!" rather than simply "the newest set in a long tradition".
