Does USANA violate SEC rules by announcing new products during private convention?

Question for the law savvy individuals in here. If USANA privately announces new products (Pure Rest) to their distributors during their 2009 annual convention instead of publicly announcing it through a press release so all 100% of shareholders could be notified, is that against SEC rules?

USANA distributors who are also USANA shareholders could have called their stock broker today and purchased USNA shares because they have insider information that the remaining shareholders don't have who didn't attend this private convention. If I am right about this, then USANA's method of announcing new products needs to be investigated by the SEC and fined if guilty.
