For a all around good camera the NEX-5n is a great choice.
You mentioned sports and well the 5n is actually a great camera for fast action it does 10fps (frames per second) in continuous burst mode. Also with a shutter speed all the way to 1/4000th of a second you'll have no problems freezing action!
The 5n also has full manual control and shutter speed and aperture priority modes. Allowing you to do rolling shots with no problem. (i feel using a shutter speed of 1/250th of a second works best for rolling shots)
Also Sony recently released the new 55-210mm good for sports (priced around $320)
