Just managed to watch the first video posted a page or two back....
The graphics look brilliant to be honest and if they can sustain a high concentration of players and limited performance impact, then it will be fantastic (take note: Bioware - this could be a lesson in how to implement a proper mmo engine)
And the day/night cycle? The battle, allbeit with c.50 players, sort of came to life at night - tracers, tank rounds....
God I hope they don't screw this up
