NB has their pre-order page up with a few varieties of hops.
I've had a pair of Nugget hop vines in my backyard for ~4 years. It is fun, looks pretty cool, and you can use it to make beer after the first year. The only downside with your own hops is that you won't know the exact alpha acids for them, but you'll be able to guess in the right ballpark.
Something to think about down the road....
I'm thinking about adding a pair of Cascade vines (the go to hop for most American brewers), but I might hold out until March to see if Freshops has something a little more unusual.
