Saturn,
I have a very large collection of EE's that i have to over winter. As far as keeping them in the pot or dry storing them... I really haven't seen much difference either way. It does matter on what type of elephant ear you are trying to store... Most alocasia do well either way except for a few species, colocasia need to be kept in the soil, and Xanthosoma don't really care. My best advice for you is that if you can leave them in their pots and put them some where that is warm enough that they will not go dormant( about 68 ' F or more). This will keep your plants from having to regrow all their roots the next spring and they will just keep growing from the size they are now. They will have to be watered every so often if you do this...
