I would be in on a Joust remake, but it would have to be at a lower price point than the current market is supporting (8k+), so based on that, I would wonder if it would be "worth" the effort considering it has almost all (no backglass) the components of a reg pin and there are better candidates at higher price points....
As for a new head to head, I think it would be cool.... But I think the price would kill it.
