The release is in testing right now. If everything goes well, JLinked v2.1 will be out on Wednesday. That will have the automatic account creation feature that you're asking about so the user can be registered without any forms.
One thing to know, the v2.1 release will not have the ability to automatically login users that have previously registered through LinkedIn. That's a feature of JFBConnect, but more difficult to do with LinkedIn. Just wanted to clarify since you mentioned "auto login". Auto registration will be there, auto login (for returning users) won't.
Hope that helps,
Alex
