I know they are working on the Core improvements and also a V5 cup that will fit the Core. Not sure if the cup will come out before the Core 2, but they are trying to get something available for the end of November.
I agree that my OG Core is still killing it, but I will gladly make it my backup unit for a Core 2. I was looking to buy a second Core anyway, and I like the idea of faster heat ups and a ceramic cup that is easier to clean than the Ti bucket. Plus it heats from both the sides and bottom.
It sounds like I might get a V5 to try out on my current Core in mid November. It is exciting to believe that the V5 cup will be compatable on both Core versions. Once I have some feedback to offer, I will create a thread for the Core 2 in the Unreleased Portable section (Unless someone beats me to it).
I think the money I was saving for a Mad Sense IH is now gonna get redirected.
