You may want to consider doing a soft launch for a test. While I agree the power hitters out there are pretty much finished with the email abuse for now, there are a few hungry ones as well that will support you if your product kicks butt.
Ask a few folks that are in deep to give your sales page a once over. If it has the right elements for a no brainer type of sale, you may get a few bites.
Usually launches take a lot of planning before a holiday. We look at what is coming out a few months ahead of time so we can plan the drop in the bucket.
With IM product launches it is that much more of a compete with the seasoned veterans that are giving tons of stuff away with the free line push around the holidays.
With that said, If you believe you have something HOT HOT HOT... Go for it. Also make sure if you are looking to grab the affiliate rock stars out there, your affiliate management is in place.
You never want to piss off the affiliates with glitch in a system. I personally just got a sting on a launch and may lose few customers over it. :'(
Such is life for the affiliates ;D
Best of everything to you and I hope you totally kill it with your launch!
If you want I will look at it.
