1. It was posted that at Gent there's 3 video screens and just one in Paris. Is it true? Or in Paris there's just one long screen and three projectors?

Yes, one long screen and three projektors

2. They finished with TEE and the encore started with Numbers or they finished with Numbers (someone posted this way)

TEE finished, then curtain goes up again, and they walked in like in the beginning of earlier concerts.

4. They still use footpedals? I remember they really use a lot them here in Brazil, to change the sound wave or something like this.

Yes, Anytime a footpedal was pressed to the limit, the corresponding sound was too loud.

5. Considering that Kling Klang is not more on stage, what's on the back of the four guys? Just the screen or the colored light are still there?

Nothing. Just the screen

6. The Robots was just pre-recorded or were the guys on the stage playing?

They were on stage, "playing"

7.Any sound when the curtains were closed? Maybe the traditional blinks and blonks.

Different Intro, not the familiar bleebs and blonks. A random sound which reminded of the Intro Sound of the kraftwerk.com website (Antenna)

How was the 'remaining' stage arranged? Linear as in Linz / ZKM 1997 or the old 'V Shape'?

There was nothing on stage. Just the 4 in a row, 4 laptops on keyboard stands with some controllers (Ralf had a keyboard). It looked like in the 1982 Model Video, or the robots at the Man-Machine Exhibition.
