I dislike being a wet blanket, but i believe there is a serious problem with leaving tubers in the ground till the following year.
I have just recently been hit with 'late blight' of some heirloom tomatoes, and looking into it via Cornell's web site it states that a vector for late blight spores is over wintered potatoes.

I will certainly be removing any wintered potatoes from now on, which I didn't do this year. Coincidently, I dug 20lbs from accidently overwintered tubers this year.
