It's not completely impossible, but in my opinion extremely unlikely that Amiga Inc. commissioned (i.e. paid for) ACK's 2005 Powervixxen LT, 2006 Powervixxen TL, 2007 "Entry Level" hardware design and/or 2007 "High-end" hardware design or purchased any of these designs (if really started let alone completed at all) at any point of time.
