As we approach the expected updates for the MacBook Pro line, we tend to start hearing about possible release dates. There are typically some false starts, so it's hard to be sure, but the first contender for this round appears to be March 1st.

Danish blogger KennethLund.dk claims to have heard from a source in one of the major Danish Apple resellers that MacBook Pro models are on tight supply but that the newly updated models will arrive on March 1st.

March 1st falls on a Tuesday which is typical for Apple's releases. The MacBook Pro was last updated in April of 2010 and is due for an update. While there had been some concern that the new models would be delayed by Intel's manufacturing issues, the latest reports claim that any delay will be minimal.

The MacBook Pro will likely adopt Intel's new Sandy Bridge processors. Many also expect that some of the models may take design cues from the MacBook Airs. The latest MacBook Air moved away from traditional hard drives and are now using smaller SSD sticks to save on space. The MacBook Air has also never included a built-in optical drive in another effort to reduce weight and space.
