I can agree with that too...
For me, the short term items are: Cokin Filters (NDs and ND Grads) and a 580EX II, and trade my Lowepro Computrekker Plus Rolling for a smaller Lowepro Vertex 100...
Long term (next year or later): replace my Sigma 18-50mm with a Canon 24-70 f2.8L (after the 70-200 2.8L i don't think i want anything other than L lenses, the auto focus speed is to die for :-D), and maybe a new body, either the 7D or 60D (when it comes out), or the 5D, though the slow FPS turns me off it a bit... I don't want to go slower than my 40D (6.5FPS)... The 1D Mk4 would be ideal but the $$$ are way too much for me as a hobbist...
