Well according to the devs the "Umbra" versions of all frames will be a "global upgrade" over regular or prime versions of frames. So basically "Umbra" is going to be the new "Prime"

Level 1 = base warframe

Level 2 = Prime Warframes

Level 3 = UMBRA

I'm hoping that the Umbra variants of the frames will have extra mod slots. THAT would make them truly OP and worth the "sacrifice" the devs are referring to. 2 extra mod slots (for a total of 12) would allow you to make some very interesting and powerful builds. Like maybe Umbra is an Upgrade path where you have to take a fully forma'd version of your Excal and you "sacrifice" all of the forma you put into it in order to create the Umbra variant. And you have to have a minimum of 5 forma invested into the frame to be able to "sacrifice" it.

Another "Sacrifice" I can see them requiring is Master ranks or standing in various factions.

OR an even more intriquing "Sacrifice" would be that Umbra warframes have the ability to "sacrifice" one of their skills for the skill of another warframe. I'd totally sacrifice radial javalin for say loki's stealth, ash's teleport kill, ivara's quiver skill, frost's snowglobe or Gara's glass shield or wall ability.
