Build it faster or wait for P6 - MLS 5.5

[crazycoder]

I am very new user in this forum. Just registered today. I want to purchase MLS 5.5. I am also new user of subliminal shop. Yet didn't used any subliminal of this site. Due to recommendation of one of my friend I am intended to purchase MLS-5.5. Can anybody tell me what topics are going to cover in this version of Maximum Learning speed? Also I found a polling system where there are two words I found "P5" and "P6". Can anybody explain me please what it mean by "P5" and "P6"? How much time would require for releasing MLS-5.5?

Thanks in advance
