I know its very late, and you probably have everything almost ready to push out, but why not react a few weeks later like what has been said.

I don't know the niche or product, but when I have promoted products online in the same niche but for different promoters, i address that the 1st Guru did BLAH BLAH BLAH and did it this way. But guru number two addressed the facts that Guru 1 did it differently because of Blah Blah Blah.

Although you might not make it huge due to another guy in the niche within the same period, at least you have a product out there that will no doubt sell for a few years to come.

I hope my comments have made sense.
All the best.
