Given Celestial Being’s immense resource issues prior to the movie, it might take them awhile to replace them. Especially since they focused most of those into 00 Qan(T) at the expense of Zabanya and Harute. They may even be down to one Original GN Drive too in a worst case scenario.

That said, they got a Raphael Dominions at some point during the Old Human Faction conflict and used it in an intervention. I suspect it will likely be within 5 years due to the conflict breaking out fairly soon the movie ended.

If they were indeed cut down to one GN Drive, it would be interesting to see how the setup of the main Meisters go. Will all four revert to GN Condensers while they keep the single one at Ptolemy or a base? Would one be equipped with it at all times? Would they also used their existing GRM Gundam Tau Drive in one of the main ones?
