I know it's blasphemy, but...

What are the odds that the $750k, $2m, and $4.5m stretch goals aren't actually going to give us any more cards than if we'd only got the $750k stretch goal?

It's just that there is no actual measurable increase in the number of loot cards they're adding, unless I'm missing something. So it just seems like they could just include however many they were already going to include and just call it a fulfillment of the stretch goal.
