Gruber got a 7.85 in measurement somewhere (I think from a past article of his).
264ppi / 7.85 * 9.7 = 326 ppi
i.e., if they made a 7.85in iPad Mini, it would have the exact same DPI as a iPhone4/4S. I can COMPLETELY see this as a viable option, as they might be able to use some of the same lines as they do for the phones and they already know 326ppi is possible.
iPad 2012 is 264 ppi at 9.7 inches
