The blurb just seems to be a very (short) generic summary of next season. It doesn't go into any details other than "Lois and Clark will continue their romance" and "Clark will do more hero things."
Yeah, no shit.
I wouldn't put much stock into it. The majority of it was written recapping this past season. It was just written so something could be written.
Not only that, but they're still billing Cassidy as 'Tess Mercer' and it seems pretty clear that Tess is dead and that her body is going to transform into something else. So yeah, I'm not putting much stock in this blurb either.
Hopefully we'll get something solid before Comic-Con, though.
