in terms of a big update, as in a redesign, or big update like g4-g5 you are right.
however, last year as i mentioned, apple announced a special event at 1 weeks notice (although word got round a bit before).
the same could be done this time round.
i personally think if apple was to release the new imacs in sept, the current line would have received a silent bump in may/jun, 8 months or so after the september o6 update, as 13 months is a long long time to leave a computer without any form of update/ price drop
Precisely.
