In future I hope they can port earlier Spike 1 DMD games like Kiss, Ghost Busters, Game of Thrones etc to the Spike 2 platform to maintain serviceability.

I have already experienced a blown 5V supply circuit on a Kiss Pro Spike 1 board, and on that occasion was lucky to have the board completely replaced, with full marks to our local Stern distributor with the game out of warranty, but this won't last forever, with earlier Spike 1's becoming unobtainium unless Stern can port these earlier DMD games up to a Spike 2 to maintain serviceability, Spike 1 games are only like 4-7 years old. Could be in for trouble if the older Spike 1 boards become impossible to source.
Would be good for Stern to offer a Spike 2 alternative just for these games specifically to keep them around longer.
Be good for George to discuss this a little.
