That's a very stupid article, the guy who wrote it knows nothing about CPUs. Just because it has 2 cores, doesnt mean it's the same a core 2 duo.
For one all the i3's are running on hyper threading and they will be using a completeley different architecture.
I do believe that they could've done a better job with their naming, it still doesnt matter about the names it's all about your performance
And you should expect i3's to come out December - January. Definatley before the end of the year.
