New G4 15" PowerBook

right now, the g4 15 inch powerbook is a year behind the 17 and 12 inch
models. ive heard rumors that apple is coming out with a new 15"
powerbook.
if this is true, i will surely wait for this notebook to be available. for
some reason, apple is very quite about future plans. does anyone have any
info about this?

thanks,
orhan
