It looks like Sony is trying something different by announcing their 1 TB PlayStation 4 after E3 instead of before or during their event. Dubbed the "Ultimate Player Edition" the unit is exactly like every PS4 sold before it except that it's got twice the storage capacity.
So far it looks like this is in Europe only but I'm expecting that we'll get the announcement of a US version later today. Those that already own a PS4 can create one of these already by going out and buying a 1TB (or larger) hard drive today but I'm not going ruin the announcement with semantics.
