Per this list on Yakface, the case assortment for wave 5 is:
2x NEW Darth Vader (Episode III)
1x NEW Sgt. Doallyn (Episode VI)
1x NEW Ree Yees (Episode VI)
2x NEW Wedge Antilles (Episode V)
2x Jedi Training Luke Skywalker (Episode V) – Wave 4 repack
2x Jedi Training Yoda (Episode V) - Wave 4 repack
1x Snowtrooper Commander (Episode V) – Wave 4 repack
1x Toryn Farr (Episode V) – Wave 4 repack
The list still states Sgt. Doallyn, though the white-suited skiff guard character was renamed Brock Starsher last year, perhaps in anticipation of this release. Whether Hasbro picks the right name is anyone's guess at this point.
This means that the Republic Trooper (The Old Republic) and AT-RT Driver will not be re-released as was apparently the initial plan. I can't say that I mind those being dropped, but I do think it's a mistake to repack the wave 4 figures so heavily and so soon – they're all getting packed two to a case in the first place already, so why bring them back here? I like the idea of them doing the waves as six figures each packed two per case, so it's too bad that they're already abandoning it after one wave. And if Toryn Farr gets to make three appearances between waves 4 and 5, why do Ree-Yees and Brock Starsher only get one each out of the gate?
