They say there are 25 figures, the 25 most popular characters. They name the figures we've already seen for the 5-packs, then they say the single packs are a series of 15 figures -- that makes 25 figures, so if the single packs included the figures we've already seen it would mean there's only 15 characters. So, basically, we're only going to see the characters we already know about in the 5-packs. Fingers crossed for some decent army builders in the 15 singles, with appropriate per-case ratios...

This also implies that we won't be getting a visored Snake Eyes...
