The largest problem with K&C, Figarti and TG is that the figures are 1/28 and the Armor is 1/30; they look silly together IMO. TCS at least makes their figures and Armor to the same scale. The same as FL, as has been stated. TBD what JJD will do with their forthcoming figures for their excellent 1/30 Jagdpanther. WB figures are 1/30 and I would assume Ken would make any future Armor the same scale. The earlier CA 2000 WB figures and Armor were both 1/32 before the figures grew to 1/30 around 2006. Ditto Eagle Design if they should decide to make figures. My guess is that in the near future there will be a shakeout of TS companies; with 1/30 becoming the predominant scale.
If there were to be some sort of shake out, I think it will be the companies with the largest sales that dominate the hobby that the other makers would gravitate their scales to, and if, as many collectors stick to one or maybe two makers. I did myself with only WB for years, when I started collecting their Zulu, then Nap etc ranges. I don't stick to any single maker any longer and collect from any maker that offer what I like.
Again if, I would assume that it would be the companies that keep up regular releases and deliver at prices more affordable as we see such makers as K&C doing with a couple of their newer ranges, 6 Day War and Tarawa Marines where K&C don't appear to have sacrificed any quality, just the old back pack! Hopefully this tread will spread to their other lines too.
FL did seem to be dipping their toe in with their mass armies idea, though that seems to have come to a halt for FL, definitely needs an injection of renewed energy there.
Other companies that are at reasonable prices for the most part are TG and TCS each with their own sculpt style and followers.
To the surprise and disappointment of some and joy of others TG changed it's size on it's Napoleonic range, though this seems to be dormant at present, will have lost collectors, but did get new ones as with Napoleonic at the time WB, FL who were arguably the leaders in that line were able to add to their armies such as Prussian Landwehr in a scale that matched up with their preferred makers.
Also they have come up with ranges not done and unlikely to have been done by others and has come out with innovations in new ranges they release.
