It's too early to tell for sure, but at least from the spoilers and news we've read, Season 5 of Grey’s Anatomy is shaping up like a total love-fest.

First and foremost, Meredith (Ellen Pompeo) and Derek (Patrick Dempsey) are finally moving in together — to the delight of millions of viewers.

But don’t count on them walking down the aisle soon.

“Wouldn’t a wedding be too predictable?” Pompeo asks, rhetorically, in the new issue of TV Guide. “Would Meredith even wear a wedding dress?”

A fair question. But even without a wedding, the on-again, off-again couple will take a break from the breaking up and finally get a chance to explore life after “happily ever after,” says creator / producer Shonda Rhimes.

“The first three episodes start the dynamic of where we are all going,” Rhimes tells TV Guide. “Meredith is trusting him and moving forward cautiously, and Derek is waiting there, saying, ‘I’m here to support you.’”

Just for kicks, how would a Mer-Der wedding look?

“Cristina would come to Vegas with Meredith and Derek,” Ellen Pompeo said. “Then I’d leave her at the slot machines and go get hitched.”

“Izzie’s got a love story — and it’s a big one, one that I’ve been kicking around in my head for a bit, one that required me to take a huge leap of faith in myself, one that is so secret that I have not told anyone. Not the writers, not anyone,” Rhimes says of the character played by Katherine Heigl.

As for Callie-Erica? And the always-conflicted George? Shonda says ...

“George (T.R. Knight) and Lexie’s (Chyler Leigh) love story is going to take an incredibly unexpected turn. Callie (Sara Ramirez) and Erica (Brooke Smith) have a love story of their own. And, yes, it includes Mark (Eric Dane).”

Lastly, Sandra Oh’s character, Cristina Yang, is finally moving past ex-fiancé Preston Burke (Isaiah Washington), who left the show after season three.

“She’s been alone for a whole season,” Rhimes says. “That’s going to change. See, there’s this military guy who ... well, you have to watch to find out."
