How long are these threads going to go on?
Seriously? You're already asking this question?
Let's see, it is July 6. We found out about romance and marriage on July 5. This is the 5th thread on the subject since yesterday.
There are 127 days, 5 hours and 13 minutes left until Skyrim is released.
Between now and then there will be approximately 27,000 threads about this new feature.
Starting from 11.11.11, and proceeding until the end of time, there will be another 18 bajillion threads about this feature, discussing such topics as everyone's favorite romance interest, how to unlock friendship, romance or marriage options with various NPCs, etc.
