The one IA is testing seems pretty unique to me. It's swatches are shaped like those on the British Multi Terrain Pattern, and the color palette seems suited for arid, semi arid and mountainous terrain. It can probably be fairly effective in areas with light foliage as well, owing to the use of shades of green.
I think similar one with a different color palette will be for areas with heavy foliage. Or, they might just stick with the current DPM for such areas. Which is just as well, because DPM is pretty effective in the jungles and such, especially when faded..
I don't think flecktarn is nearly as versatile as multicam, which is why multicam is so widely used.
The one we are trialing or some variation of it will be selected for service soon and be issued in 5-6 years. It'll see widespread use in another 8-9 years, maybe. However, front line troops might get it much sooner.
