Its interesting their going with IS Omni. I guess about time for that, I wish they did more original design, like Sunder. At least its stands out, I think one my issues with (side from them having big design issues on purpose) 1st generation ones were mostly just clones of existing mechs.
I guess they'd need be careful, since these things need to sell. The Raptor was prototype, but it was too thin armored to be usable or staying power. While the Strider is very flawed thin armor and really not great of choices of configurations. Owens had single heat sinks only, with limited pod space.
If they go with 1st gen OmniMechs, aside maybe the Sunder, I could see them doing the Blackjack or even the Firestarter since they turned out to be more servicable machines. Unless they plan skip the 1st generation OmniMechs IS made except for Black Hawk KU
