The prolonged wait for updated MacBook Pros continue without any major hints at when they might arrive. A report last week suggested that a shortage of Intel notebook chips could be contributing to the delay.

MacRumors has heard that the MacBook Pro supplies to retailers have abruptly become constrained, possibly suggesting that updates could be imminent.

Meanwhile, one MacRumors reader emailed Steve Jobs directly about concerns about how long he's had to wait for the new MacBook Pro updates and Apple's recent focus on the iPad. He wrote "I recognise the need for secrecy etc but I am really losing heart in the lack of vision for the MBP and Mac Pros. Not expecting a response but as someone who has personally switched dozens of people onto the mac way this is a sad email for me to compose."

As he's been occasionally known to do, Steve Jobs reportedly responded with a short reply that simply said "Not to worry."
