Guild Wars 2

Was just wondering if the expansion packs we’ll get in the future have new races in them? and if yes, will they add new classes for them too?
asking becouse im addicted on making alts all the time but now I’v started thinking if a tengu thief would be possible in the future :P and similiar ideas^^

Also, has anet said anything of possible race switches (Yes yes yes its unreal and doesnt fit the lote etcetcetc….) in the black lion? considering many people make and level their toons to 80 now, it would be kinda stupid if they only added races in the future and no new classes for it and no way to switch race instead of leveling it all the way up again?

Thanks for reading and thanks in advance for replies^^
