But there will be directors cuts/ Extended version of all the films after they finish the 7th movie, and Peeves will be in 1st one.

I agree, I'm sure they will release extended cuts since they shot loads of extra stuff for GOF and also apparently for OOTP (the director said he'd have to cut it down by at least 40 min to meet the required time), there is also a quote from the guy how plays Percy saying Chris Columbus intends to include the Peeves stuff in a "director's cut". Although I think the third film will be the least extended as it seems to be missing least where as GOF was obviously missing a lot.

I have never heard that they shot scenes with peeves for the third film, it's not in the version of the script that I have read which does include Sirius breaking into the common room, and the much needed explanation from Lupin that they made the map and why the patronus is a stag.

If they did do senes with peeves for the third film it definitely shows an intention to do extended cuts.
