It's all dependent upon the availability of product, like what rw3 mentioned. It all depends, some things had a long wait, like ipad 2's had like a 6 month wait or something like that but some things like the 2010 Mac Pro only had 1 month or a few weeks wait.
Seeing how hot this laptop is right now, i think you are probably gonna wait several months until it's available on the employee store.
