If I understand your questions correctly, the xbox 360 and PS3 (can't speak for WiiU) output at 540p (xbox 360) and 720p (ps3). The FPS depends on the game. Most run at 30FPS and there are a few that supposedly run at 60FPS (COD Black Ops 2).
Both consoles will upscale to 720 & 1080 but it's not their "native resolution".
The Xbox 360 and PS3 are both capable of 1080p output but 95% of games on both systems are released with 720p as the native resolution. I don't know where you heard 540p from must have been from a PS3 fanboy.
