Haha. My first thought seeing this title was that it would be a new product announcement. Boooo!
I think ACA 1231/42MHz is really a new accelerator.
It's being sold for the first time, one month "old" or so.
Actually it's accelerator card from the future:
"Today I’ve got some news concerning a hardware upgrade for the Amiga 1200. It turns out that a new accelerator card will be available for purchase shortly. Vesalia, which is a popular Amiga shop in Germany, estimates that it will arrive on the 1st of March 2012."
