Mods available at launch

Hi,

Will any mods be available at launch? Or will we have to wait a few days/weeks/months/years so the old mods can be ported to BGEE? I ask because I'll preorder BGEE and play it at launch, and that's probably gonna be my only playthrough (I don't want to spend too much time on it ...), so It'd be nice if I could use a few mods.
