HoT Standard Char slot
The only thing they have said on it I know of is; you have to pre-purchase and register it before launch I believe to get the extra character slot.
If I pre purchase Heart of Thorns Standard Edition this weekend, am I still eligible for the free character slot? Or has that offer expired?
When did you buy the game?
Did you buy it directly from Anet or through a retailer?
Free character slot
If you registered your core Guild Wars 2 game before January 23, 2015 and register a pre-purchase serial code for Heart of Thorns any time before the expansion is released, you’ll receive a free character slot! Once you apply a pre-purchase serial code, you’ll be eligible for the slot regardless of where you bought the core game.
If the serial code you used to register the core game came from a retail vendor (rather than buy.guildwars2.com or in-game) and was applied to your account between January 23, 2015 and June 16, 2015, you’ll also be eligible for a free character slot if you apply a Heart of Thorns pre-purchase serial code before the expansion release.
All accounts that become eligible by July 9 will have their free character slot applied by July 10. Eligible accounts that are upgraded with a pre-purchase serial code after July 10 will receive their slots on a weekly basis after that.

Bought it through Anet
You should get your free slot then, but it will take a or so for some verification thing so they can make sure you have a legit code or something like that.

As long as you bought it before January 23, 1015 then you should get the character slot.
