I've bought them and will continue to do so with the ones that haven't yet been released.
For me the blurring is fairly trivial. Compared to some of the old 720p cards (which I watch regularly) the quality is still superb.
Totem have found the problem with the camera and fixed it for recent/future cards. The only fix they have for the currently affected cards is post process sharpening which they have applied to some of the cards but people are still *****.
As indicated they have put a disclaimer on the affected cards so noone has to buy them if they don't want to.
As for the low ratings that is down to the rating system which personally I don't think is fit for purpose. I'm surprised that people still use it. I don't. I make my own mind up about cards, I don't let other people decide for me.
