Does the storyline end exactly at level 50 or it goes on?

I'm about level 40 with my character, and still in Act 2. I'm wondering if the storyline (Act 3 and Epilogue) finish pretty much exactly at the time you get the 50th level, or does the storyline continues for a couple of hours of gameplay after you reached the level cap?

Solution 1:

I've dinged 50 during the final class storyline mission on both of my level 50's, but based on conversations with others, that seems to be a lucky coincidence.

The class storyline continues through Corellia, the final planet, which is tuned for levels 48-50, and generally ends with a series of visits to class specific locales (think space stations, ships, obscure planet only for your class, that sort of thing), tuned for a max level or near max level character.

That said, you could easily hit 50 well before doing it if you have a lot of 'extracurricular (PvP, FP's, bonus series, space missions, etc.)' XP coming in, or get there much sooner with a high level buddy tagging along to kill things for you, so YMMV.

Solution 2:

I have done both, hit 50 before finishing the class quest and finished the class quest before 50.
