On a dummy demo's dps is very similar to afflictions, from my testing it normally is slightly higher. Affliction makes up for this at the end by having a far superior execute, however drain soul execute rarely comes into play in PvP anyways.
As for as SB SW, Haunt, MG being burst...it isn't, not like chaos bolt or meta. With Haunt \ MG you basically are cycling between 90% average dps and 110% average dps, but there is no phase in affliction where you are suddenly doing 200% average dps. With meta you get that kind of burst. Don't confuse low ramp up times with burst.
As far as multidotting, currently Demo actually sims out higher, however in pvp it doesn't have the dispel protection that UA offers. We will have to see how the new dispel cooldowns actually feel in pvp though, it might not end up being as big of deal to not have dispel protection as it is on live.
And then you go into mobility wise, demo has insane mobility Fel Flame is nearly the same dps as shadow bolt, and generates nearly identicle fury per cast time. The only downside to it is increase mana usage. Plus the fact that demonic slash \ touch of chaos being instant makes us very difficult to lock down when we are in 'burst mode'. Where as affliction if you aren't channeling either DS \ or MG you are losing a very solid amount of damage, which makes you locked into taking Kil'jaeden's cunning which throws away a decent amount of passive damage from AV.
