Poor reliability of spike games could have a detrimental effect to value of games. If they turn out to have some chronic flaw that shows up in all the games 5 years now (ie wpc resets, burned GI, etc), but the flaw is on a board not manufactured anymore and not easily serviced could result and games turning into giant paperweights starting a free fall of game prices. No one pay 8k for something that might fail and be unfixable.
My early feeling about the spike system is not good... I hope I am wrong and it is a solid platform.
