TOG apparently used to be NC, and faction loyalty in this game is so extreme that I dont think they would be willing to change at all. I myself have never played the original Planetside, and from what I have seen I am very keen on the Vanu.
For me its not the easy mode aspect of it. Rather its the fact that I can right now log into a dozen different shooters that use conventional weapons, but that I barely own any with the more futuristic stuff. I cant even think of how many other FPS out there other than BF2142 have used hovertanks for example. I suspect that I wont be able to use this sort of gear in a good FPS for a while, so this is my chance to just have a good time with it.
On the other hand the vast majority of TOG players that are interested in PS2 so far will definitely be playing NC. The temptation is there to just go NC as well. Consolidating all of TOG into one faction on one server would at least mean that we would have a presence in the game for years to come. We will have to see what sort of interest there is in the game before we seriously discuss splitting up TOG into multiple factions.
In regards to skill level, I think the game will be have about the same learning curve regardless of the side. From looking at the videos so far I dont even think that the bullet drop is that bad at all. Yes NC vehicles seem to handle like bricks, but at least its hard to screw up moving slowly in a tracked tank. The VS Scythe does look easy to operate, but to make up for it I think that the Magrider will be an much more difficult tank to use effectively.
For now I say lets just wait and see. If the game is good then hype will start to build, and by the time open beta hits we will have a much better idea of how many players we might be looking at.
