I'm considering buying an AC-87u or AC-68u to replace my current N56u. However, I'm not in a huge hurry at the moment; I could stand to wait a few months or even a year. My understanding is that the tech in the AC-87u (wave 2 or whatever) is still pretty new. Might ASUS release a hardware revision of the AC-87u, or even a new model that is similarly powerful but significantly more efficient/reliable, in the future? Or is the product roadmap basically just a progression of more and more...
