>>7264155I'm willing to give FH a little leeway on their projects since they've been putting so much focus on getting Overlord just right. Of course, he's shaping up to be just about ready for [spoiler:lit]prime[/spoiler:lit] time for early next year, so it could be about the point that something new is shown off. They'll be at the upcoming SGC in mid-December, and being a Chinese company I'd say this is the best opportunity there would be for them to show us something new. There's also their Roadbuster to consider, which numerically comes before Megatron.
>>7264380You identified them correctly. For my initial thoughts on Gunfighter, see
>>7262954 (I only got him in yesterday afternoon, and had work early on this morning, so have only had a little bit of handling). Sentinel is a bit of an odd duck. Firstly, he's a core robot (Gentoo) that's similar to the Hasbro Generations G2 Prime. The reason for that is they initially developed a trailer that broke down into armor pieces for that particular release. There's a partially armored mode which he's in, as well as a fully armored mode using all the trailer pieces, pictured here; which I find just a bit too busy for my liking.
