So the final content patch has been live for a few days but I've just now fired it up and...
1) ...holy hell, the SLDF mechs have engine doubles now.
2) There is an Inferno Carrier.
3) Proto-TSM Raven.
4) ECM Cataphract.
5) Can confirm the escort missions now clear once you kill all of the OPFOR.
It is pretty nice for a send-off.
