I have the rugged and it works just fine with the extended battery.
A little strange that some dealers reportedly have the otterbox and are already selling them, but otterbox themselves, who sell immediately without giving dealers free days, are not even selling them yet...
And if you have been reading the posts on otterbox's facebook page, there isn't even a sniff of a release date.
BUT the price is right on ebay
BUT that is a little fishy, too
