Wii U has the greatest potential for progression because half of its RAM is locked away. If Nintendo eventually unlocks even half of it, that's a massive increase as a percentage of RAM available to developers.
Yes, the PS4 can have more RAM unlocked as well but as a percentage of the total RAM on the system, it's not as big of an increase which won't yield as dramatic results.
I think the real progression though may be how indies progress on consoles through the generation. With the increase in tools and conversion scripts, they will show some seriously marked improvement year over year.
