So there's been some news for the F2P changes this week. For one, you can now see how many Cartel Coins you'll be granted at F2P's launch.
More importantly, they updated the features page to be more specific.
Subscription players obviously get full access to everything. So I'll just list the F2P info.
Story 1-50 content: Full Access.
Character Creation: Limited Access to options (doesn't further specify, unfortunately).
Operations: No access unless you purchase a weekly pass with Cartel Coins
Warzones: 3 per week, weekly passes available.
Flashpoints: Full rewards from 3 per week, with weekly passes available to unlock full rewards from all.
Space Missions: 3 per week, or purchase a weekly pass.
Cargo Hold: "Gain and expand" the cargo hold with cartel coins.
Inventory: Can only expand inventory with Cartel Coins, not credits.
Crew Skills: One crew skill slot, and additional slots can be purchased (up to three)
Quick Travel: Longer QT Cooldown (Sub will be reduced), or you can purchase a permanent reduction.
Emergency Fleet Pass: NO ACCESS, unless you purchase authorization.
Death: Revive at the nearest med center, or a total of five times in field. Can purchase more revives from store.
Game Login: No priority login.
Item Equipping: Cannot equip most purple items without purchasing a license.
This is way worse than I expected it to be. I never imagined you'd be limited to weekly passes...
