Because of the worldwide chip shortage, the KRAKEN card for Amiga 3000 and Amiga 4000 will not be built as planned. Apollo Team canceled the link for preorder too and the production of the KRAKEN is postponed until FPGAs are available again. The new V4 STANDALONE and FIREBIRD cards are still available to be ordered on Apollo Team Store here.
The announcement on Amitopia that you can read here is postponed. For further information about the FPGA cards for Amiga 3000 and Amiga 4000. Make sure you follow Amitopia Amiga Magazine website.
