while i'm all for supporting manufacturers' ventures into WWI, and more detail is better, and a Camel's a safe way to test the waters, i will never pay money for anything in 1/48. even if it's the Best Kit In The Universe Of My Favorite Subject.
when i got interested in the hobby again, i made a large spreadsheet of all the subjects i'm interested in, and their sizes at various scales from 1/1 down to 1/2400, with the goal of arriving at one scale for everything. the closest i came was 1/72, which is still my main scale. however, when someone said the skipper of the Revell PT-109 looked like Shafty Kennedy, i looked at the figure. it didn't. so i chose 1/32 for 'close ups.'
1/48 is too large for ships and too small for figures. that said, everyone who cares about constant scale is likely to come up with a different answer, and i'm happy for the folks who focus on 1/48, as they were kinda left behind by the whole WNW thing.
i do expect 1/32 is here to stay for WWI stuff, however.
