So if you go to CS in game you can see a tab for Season 1 has tidbits like:

* tier rewards depending on rank. looks like there is going to be more then one and you will always get the reward that is lower then yours. also looks like rewards will be given at the end of the season.

* Season 1 ends with 2.7

*SWTOR leaderboards are categorized by Advanced Class

Well i hope this wasn't already posted but i did search and found nothing. Hope this helps some concerns.
