Two new Platinum packs coming?

[griffin]

From Hong Kong I think, comes a listing of upcoming Movie Platinum multi-packs, with two previously unknown packs...

Platinum Edition - 1st Ed Optimus w/ trailer & Stinger
Platinum Edition - Generations DinoBots 5-pack Black & Grey

The first one is a bit of an odd pairing, and I wonder if the trailer will be the one being released in Japan in the AL line... or a previous Movie trailer.
The second set sounds like it might be more movie-accurate "metallic grey", but then, why have five, as there were only four in the Movie. If they are a Gen1 5-pack, why black & grey? They could still do a Gen1 coloured set that uses matte grey to avoid being similar to the SDCC pack of shiny silver figures.

EDIT - okay, it is apparently the five "Gen1" Dinobots (2 Voyagers, 3 Deluxe), but still not sure about the colour scheme though.

EDIT - not the five Gen1 Dinobots. Instead, Grimlock, Scorn, Slug, Strafe, Slog.
