The fact that I would want to produce performance benchmarks of the game, showing how it runs on different hardware, and then publish that online to help people know what they need to run the game.
But shucks, forgot about it. Would of been a great pitch.
No point with making benchmarks. First off public releases havent had any fancy graphic options settings and as for the benchmark, for that all they have to do is try the game on 8+ year old rig with low specs and it will be no brainer that anything above will work. Dont know about latest builds but from previous public tests it worked just fine on 512MB opengl 4.0 GPU, so the question is if it will work with GPU's with opengl 3.x and below. For example Intel Extreme Graphics 2 had problems like no textures
As for minimum ammount of ram well it all depends how much stuff people are running in the background, some have <2GB, others more, but in the end if someone has at least 1GB or more free RAM (not counting in use by system) it should be ok.
Also the big factor is ammount of people around you since this IS a MMO after all. The more people around you (on your screen) the higher the demand. So in the end a benchmark would not be of much use. As for minimum specs, if there will be anything mentioned, it will still be dependant by the people near you.
