I was just thinking and wanted to see what other people are thinking. they announced the bases they will be selling a little while ago and I look forward to them. with luck, this means we might get some rules soon so we can have official games to go with the minis.
If we do get official rules it makes me wonder if we will be playing with mass or skirmish combat systems. I'm personally fond of 10-20 unit skirmishes, but with the large army boxes, I think mass combat is what they would shoot for. I'm fairly confident death fields will get a system of its own, but for other lines it is less likely.
I imagine first empires, decline and fall, blood oaths, and renaissance could be placed together. this would be a mostly melee pre-gun or early gun system. classic fantasy has enough figures it could be it's own, but could also be placed in this category.
napoleons wars already have quite a few systems out there if i recall right. so it's likely not as high of a priority for this mind set. it could maybe even bundle with imperial conquests but not likely. and both will need to wait for more sets in the range.
world war 1 and 2 would also probably need separate systems, but i recon those need to wait for a bigger lineup.
ideally, i'd want all the ranges to be bigger and have their own system, but i bet that just requires a lot more waiting at the moment. even death fields which i suspect is closest to a rules set probably wait for 2-5 more releases. I would suggest some sort of "universal system" to cheat the limits of company size and time, but universal systems rarely sell great.
