Question about Factions with Old Char vs New

With the new GW:Factions coming out and I currently have 4 char's which have beat all missions in game, will I have to delete my original char's in order to Create 2 new characters? or will there be 2 empty spaces incase I would like to build 2 new chars and level them, also would the 2 new chars start pre-searing and be able to go through Tyria before going into the new expansion land?

There will be at least 1 new character slot with the advent of Factions. (Not sure about your second question)

big debate still going on about the char slots and a.net have only said 1 upto now but possibly more.and factions is said to have its own pre-searing style area to start new chars in.

I know the chars from GW can go into the Factions area freely.. but can the Factions chars go back to the regular GW areas?

if they own both the chap1 and chap2

I believe Guildwars factions will release two charicter slots for Factions.

So far we've always been 2 charicter slot short of being able to make every primary class. (Mesmer, Warrior, Ranger, Necromancer, Elementalist, Monk)

So if they add 2 new Charicters, that means (in my train of thought) that they will add 2 more slots, thus still keeping their old setup implimented. Only being able to make 6 of the 8 charicter options, instead of 4 of the 6 we have now.

I think they should add 2. Otherwise it would be kind of off to only add 1, but adding 2 new charicters.
