More details coming from AmigaKit:

"The pricing of the PA-SEMI CPU is volatile unfortunately- the last production run we absorbed half the price increase and Trevor kindly absorbed the other half to ensure that the batch was produced for waiting customers. This time we will once again work hard to keep the price static for customers."
