Hah, I'd forgotten about the gameband.
It's a fair point about ignore any discounts, given you don't know when this will come out but it's likely to be at least a year. You'd have to take some pretty crazy investments with savings rates as they are to offset that saving, but pretty much any risk is better than the risk of getting one of these I reckon. And once it releases and you see what it actually is, you might not want it anyway.
As far as I know regarding the Pyra, we're not getting any discounts at all. Given how long it's taken we could have made interest on that money, but we invested it to help the Pyra team out, so we knew what we were in for. In comparison Atari has got many times what it asked for on kickstarter so can better afford people backing out. And the odds of getting a Pyra eventually are still greater than ever getting something looking like this.
