Ivy Bridge i7 3770k Newegg low supply on release date?

Difficult to say...

I don't really expect the demand for Ivy Bridge CPUs to be very high since overall it only outperforms Sandy Bridge CPUs by a small margin. Therefore, most people who already have a Sandy Bridge CPU will likely not upgrade. I have not heard of any production issues, but then again the vast majority of the initial shipment of IB CPUs will be going to system builders like Dell and HP.

Haswell will be a different story since it is a totally new architecture that is going to be released in March 2013 (unless there are delays). I intend on staying out of the feeding frenzy and upgrade to Haswell in mid 2013.

If you were eagerly waiting to order the Ivy Bridge CPU (like me) what time do you think you would check Newegg to see if they have them?

As for low supply on release date?
Even if the supply is 'high' but the demand is still higher - it has the same effect.
They'll run out before everyone that wants one gets theirs.
Be sure to check for alternate sources of supply.
