ST made an official press release concerning episode 4 today.
1. A demo license will remain Episode I & II only, up to level 20 for 15 days.
2. on the 30th, ST will launch a page for purchasing an activation code for the download edition to add Episode IV, at 3000 yen (about $30) (guess I messed up on that one guys. sorry. We must have been on two different topics when I spoke to Armion)
3. The music cd will not be included with the download edition. (I'd suspect that things would still be in .OGG tho, so just get winamp and convert them to .wav)
4. Only 1 activation key can be linked to an account, and once activated, can not be used on any other accounts.
5. You can continue to play Episode I & II without purchasing an activation key
6. (would someone check me on this?) Purchasing either the retail version or the download version activation keys will give the player a new rare item. 150 new items are being added to episode IV, and they will be recognized even with players who don't have an activation key.
7. February 3rd ST plans a maintenance to activate Episode IV. Please do not connect at this time. The maintenance and game reactivations have no set ending time so please be patient.
