Just checked my TU dispute and got this message. Probably same as what OP received. Nothing new on Credit Karma, but hoping it's a good sign that the BK is dropping early. First time I ever saw this kind of message about an open TU dispute.

Awesome news!!! Keep in mind that EQ and EX will delete one month early.... So, I'll be very very shortly!
For some reason my BK never showed on my EQ report, but did show on EX. Couldn't open a dispute for EX; no report number. Had to request by snail mail. If not off, then I'll open a dispute online. Thanks again! BTW, did FICO report the change yet? Still waiting for mine.

I haven't received any alerts from myFICO yet. But, all my other FAKO scores have gone up. My Discover statement cuts on Saturday so I may get my TU FICO that way instead of here. Go figure!
