From an article on Car & Driver online today:::
As we’ve previously reported based on Lexus trademark filings, look for the turbo NX to carry the NX200T badge, while the hybrid should utilize the NX300h moniker. Both cars should appear early next year in production form before going on sale as 2015 models.

 

All other sources I've seen so far suggest a Fall to late 2014 release, ~November time frame. Maybe this is for specific markets first, or perhaps one model might appear over the other first (200t or 300h) - that we don't know. We should have more details either this Friday when some more info should be released on the NX or on April 20th at the unveil in Beijing.
