According to the Ares Games website Upcoming page the Wave 4 ships are going to be release in two batches - the 34-guns Mahonesa class Frigates and the 64-guns Ardent/ Intrepid/ Inflexible Ships-of-the-line in September followed by the 80-guns Bucentaure/Tonnant Ships-of-the-Line and the Bonhomme Richard / Ex-East Indiamen in October.

However, since September is nearly gone without any sign of the first two classes of ship, what do we believe?

Incidentally, has anyone seen any evidence of the re-release of the Starter Sets, yet?
