Free accounts will be restricted to three or four character slots depending on the region as well as longer dungeon cool-down times. Characters will be allowed 72 storage slots.
TERA is also getting a major content update in the near future. The patch includes a revamped political system, "content centered around guilds and the community," large-scale PvP events, sieges and airships, and new dungeons. NHN has released a story-focused teaser video for the update which you can view after the cut (there are no subtitles). Thus far En Masse has not commented on any business model changes for the American client.
