I read the available information the same as Rustler. I think most recent pricing (from US distributors) included the 2.5% existing tariff so kits delivered may have an additional 7.5% which while unfortunate is not as bad as what was originally proposed. This is of direct interest to me also as I have a kit that is targeted to deliver in the US around late summer early fall. Of course the "negotiations" could change or go off track. One thing I have investigated is the possibility of "parking" the kit in a bonded warehouse in England and slowing the delivery. I hope it doesn't come to that since that would be like trying to "time" the stock market.
