I don't think there will even be a Cannabis Cup this year, atleast not in Netherlands. For one, the foreigners(besides Germans) are not allowed to purchase/smoke MJ from the coffee shops anymore and also last years Cannabis Cup was raided by the Police.
Foreigners can still buy/smoke weed in Amsterdam proper, at least through the end of this year.
On a Dutch cup, HT magazine has said there will be one for this year. . .but of course that's what they will say right up until the moment they say something else!
In the meantime, HT has already started hosting alternative "medical" cups in the USA, to hedge their bets.
The Cannabis Cup is huge business for the industry, acting as a sort of trade show.
My advice to the original poster is that as a small "no-name" breeder (ie one who doesn't spend a lot of money advertising in High Times) you probably won't even be allowed to enter the "contest". (If, indeed, it even really *IS* a "contest". . .some have alleged it isn't).
