There's more than you can remember. From the day after Joffrey's wedding you still have quite a bit of political intrigue, a trial over some issue, several deaths of moderate to big characters, plus outside of King's landing you have the happenings at the wall, the happenings around Dany (and Dany's storyline is lagging behind where it was in the book at this point unless I'm mistaken, so I expect some focus on her), plus we have the extra-literary storylines that weren't in the book as far as Aysha who is going after Theon right now (in the books Theon disappeared the day Winterfell fell to the Boltons and doesn't appear again for a few books), as well as I think we are going to follow Stannis more closely than the books where he disapeared for a time as well.
