I think that there will be some sort of refresh in September, but it will still be an iPad 2. Maybe a $50-$100 price drop across all models, different colored backs, available on T-Mobile and Sprint, or something else like that that doesn't really replace the iPad 2, but would ensure strong holiday sales.
I wish they produced an ALL black model, leaving a 2mm thin aluminum rim along the edges.
Could you imagine seeing someone else holding it from afar?
The thing would actually look like its 2mm thin!!
