I've got the Core Boxed Set, Adventurer's Vault and FRPG (even though I don't use the setting).
I am planning on buying each years new set of corebooks, as well as the Martial Powers book coming out. Probably Manual of The Planes as well, and just mainly crunch books. I am also subscribing to DDI.
I will say I'm shocked at how many people actually purchased the character sheets, I mean from what I hear they are almost universally regarded as sub-par...it makes me wonder if this was a case of pre-ordering before the comments, the "collector"' mentality or something else.
