Thanks for your input. I realize that apple only knows for sure. Some people however have better estimates than others based on Ivy bridge release dates and product cycle information that is a bit more in depth than the Buyer's Guide which contains mostly common/generic information.
Personally, I speculate April, but was wondering if March would be in the realm of possibility. However, I think that iPad 3 will be their big Q1 product, and the macbook line will be their big Q2 product.
