Wires? Yea, we still need wires for some things. Apple doesn't do stuff that's not going to be a good experience.
Memory? ...don't know, don't care how much memory is in my original iPad - I only care that it performs well - and it does.
Screen resolution? Don't know what rumors they were following, but it's completely impractical today to put a retina display on an iPad-sized screen. Wait for it.
Megapixels? ...pointless fluff marketing numbers.
Storage space? I bought a 32gb and wish I had saved the 100 bucks. All my content is on my Mac which has many hundreds of GB of storage.
These all seem deep in nitpick territory. This is a consumer device - like your TV or your microwave. Post-PC, remember?
