It's a rumour. Probably got a few clicks, probably not worth more than that.
I'd be surprised if there's any truth in it because even if they find the cause and can be 100% sure it's fixed it's a PR risk to remind people of this again, the reputation of the device will ensure that sales won't be spectacular and price will have to be lowered, and unless they could do it very early in the new year it would distract from the next flagship release. So I wouldn't waste time on it if I were them, but who knows?
