For the most part, they'll be separate universes. The 25A, because they are in the old outfits, will be part of a dio line called GI Joe Chronicles. The middle child era of figures will be called something along the lines of GI Joe Modern Age. THere'll be very small crossover. ie; 25A Destro is perfect in my eyes as is the CLegion Stormy so those will be my standards for THOSE characters. But someone like, oh, Roadblock... I'll use a different figure.
