Total speculation...but I wonder if a new Mini does come along if they'll use the same 7.7" square form factor as Apple TV and TimePort instead of the old 6.5" size used by existing Mac Mini and Airport Extreme. I suppose the advantage of a slightly bigger box, apart from family resemblance to other new Apple products, would be a bit more space for a larger hard drive, etc. But what do I know, this is just idle speculation. I hope a new mini comes soon, though. I'd buy one in a second if it could do 4GB RAM and had 802.11n.
