Sony just announced the updated versions to the NEX 5n that will probably be available in OKC by the time you get there. They are the NEX 5r and NEX 6. They look great but if the price is good for the NEX 5n, you wouldn't be going wrong. I'm in no way upset that I didn't wait.
If you are mainly interested in action shooting like sports, pets, kids then you might want to look at something different. It's not that the NEX series is bad at this, it just isn't it's strength. For me I like portraits, landscapes and street shooting which the NEX is great at. For street shooting it's unobtrusive and nowhere near as intimidation as pointing a big DSLR at someone.
Here are a couple of pics from today in Martyrs Park
