Based on the Apple style and the craze in malaysia , the most it take is 3 months++ for the hype slow down like the recent iPad 2 , as the stocks are more than demands now since early August ( launch date 29th April ). Also play the role in killing the hype is how Apple store MY handle the shipping time. If they can ship from 1 - 3 business days , there wont be so much queuing anymore.
Hope this year iPhone 5 launching by maxis will be held at same venue and do some improvement on their arrangement and queue system, last year the last customer get their iphone4 at around 7 AM and i am the last 5th customer walking out The Garden at 6AM++ . Dont know if we are lucky enough to get the same launch date as singapore or not this year , but chances are high because the recent ipad2 success in malaysia i think apple will consider us in latest 2nd batch of country to release iphone 5.
