ACToys in China, which usually gets a sneak peak at soon to be released figures, is indicating that the upcoming Binaltech Convoy weighs .9 kg. (This weight may include the packaging.) This may bring relief to some fans as it indicates that the figure will have a fair bit of die-cast parts.
In comparison, you can see below the weight for Binaltech Black Convoy, which was die-cast and plastic vs KISS Convoy, which was all plastic.
