I'm rather hoping they will do an Eighth Army set at some point, the conversion potential, especially when combined with these would be magnificent.
One thing does intrigue me though. A friend pointed out that the weapons on the plastic sprues are considerably finer and better scaled than those in their lead ranges, so there is quite an obvious disparity between the two. I agreed that it seems odd that they didn't make some compromises with the plastics so they fitted better with their own lead figures.
