Yes the new NEX-5R and NEX-6 are arriving soon but those will cost you at least $200-$300 more when they are released. The main difference being the new models will have slightly faster focusing (probably), Wifi and apps.
The main criticism of NEX cameras is normally the lack of quality lenses, however there are a number of lenses to be released in the next 3 to 9 months:
Zeiss lenses:
12mm f/2.8 Distagon
32mm f/1.8 Planar
50mm f/2.8 macro

Sony lenses:
16-50mm f/3.5-5.6 OSS pancake powerzoom
10-18mm f/4.0 OSS
35mm f/1.8 OSS
