I am in the immediate market for a new Macbook Pro. I was going to buy the base model 15 inch. While researching my decision I soon learned that Apple plans to refresh the MBP lineup with an option for new VEGA chips. I also took notice that Best Buy has a significant discount on them making me wonder if Apple will be moving on from the 555X and perhaps moving the 560X down to the base model. I was hoping to make my purchase tonight as I need it for weekend travel but I definitely do not want to spend over 2k if it will be replaced in a mere week. Thoughts?
