At $499 to $799, I doubt there will be anything "elite" about them. This is why there is no mention of specs. Resolution, panel type, CPU, GPU, memory, battery capacity, even ease of upgrade-ability would be an elite feature. HP has a bad habit of making laptops with no user access and closed backs.
I just saw some more detailed info on these. The EliteBooks have options for good displays (instead of the crappy base-models displays) and they all will have excellent drop survival and liquid spillage mitigation... and cost over $1K for what's expected to be the most commonly purchased models.
