Live 4 Compatible With Jampacks Options

[moneytrain]

hi,
i'm considering buying live 4, but was wondering about the compatibility. as i don't know how many samples and loops come with the package (does anyone have any idea how many gigs of samples and loop there are in live 4), i was wondering which formats live supports. i read somewhere that is needs to be .aiff or .wav, and then something about VST and Audio Units. i have no clue whether programs like the apple jampacks will be supported or not.

appreciate your help,

(p)

p.s.: would you recommend live 4 or reason 2.5 (i'm into hip hop, chill out and electronica)
