No it will not. The file is available for download still.
New users who want to download and install this are out of luck. Existing users who either got an invite to the beta trial or just got lucky can continue to use this. Creating a new account with a valid BBID has been blocked since the 18th.
I wouldn't worry too much about it Knotty, BlackBerry isn't.
