I got blight on my tomatoes last year - I grew them in the ground. I don't even think we got one ripe tomato last year. It was a really very wet season.
Try not to let the tomatoes sit in water - make sure drainage is good and don't water too much. Let that soil get dry and let them get plenty of sun.
We don't have blight this year on our tomatoes - I heard they need 1 inch of water a week. We never watered them this summer, except for when they were just growing and through a couple of really dry spells. We've had TONS of great tomatoes.
Not the same with our powdery mildew though (I posted re: that) I hope you have better luck next year!
Here's a post I found about blight. Since your stuff are in pots, I'd just throw out the soil and also clean the pot really well (bleach).
"1. give your soil a dosage of lime as your soil could lack nutrients in which the fungus prefers. 2. grow your tomatoes in a different position as blight will still remain in the soil, this will hopefully give your toms a better chance. 3. take with you a tub of soapy water and remove the blighted leaves, washing your hands in between every one you have plucked! A slow and laborious process but one which might give you better rewards in the end, fingers crossed." - source: http://www.wildaboutbritain.co.uk/forums/wildlife-gardening/46882-blight-soil.html
