Waiting to see exactly how high above their original ~$350 target price the thing will go for before I decide whether this is interesting/exciting news or not.

Pricepoint determines market adoption. It could be the "best thing ever" at $1k and no normal consumer would buy one, leading to a drying up of interest and market adoption, resulting in a dead product. Given who's supporting it, granted, that's not a very likely outcome, but it's still something to keep in mind.
