Just to keep things straight, yesterday was NOT a "probable cause" hearing. It was a hearing to address a Writ of Habeas Corpus (basically to challenge the size of the bond specified), plus several other motions. While it ultimately covered some of the same ground as a "probable cause" hearing might cover, it was not one.
ETA - There was not and will not be a "probable cause" hearing in this case. That is not required, since LE obtained an arrest warrant as we have been discussing for quite some time. An arrest warrant and a probable cause hearing are two alternatives provided to allow the same result.
