Some leaks online, looks like the NOTE 2 will be:

- officially revealed in 15th August
- available (international) in September-October period
- codename GT-N7100
- Android 4.0.4 with TouchWizz 5
- Have the same SoC as the SGS3 (Exynos 4412)
- Slightly overclocked cpu (1.6GHz) and gpu (Mali-400)
- Larger 2GB RAM

- Super Amoled Plus tech (not PenTile)
- 1280 x 720 resolution
- On-screen Navigation Buttons
- Slightly larger 5.5inch display
- Slightly Wider, Thinner, about the same Height.
- 12MP camera
- NFC
- Possibly bigger battery (between 2500 and 3200mAh)

... it's more like a NOTE1.5 or SGS 3.5 than anything else. I think its safe to "pass" on this, if you have the original NOTE.
This revelation isn't a shock to me, but a big disappointment since I was hoping for a genuine NOTE 2:
