I have the alfa and it is a cracking bit of kit.
Personally I wouldnt wait for the following reasons:
- Many companies are slow adopters to this sort of technology
- Unless a complete refresh was planned I am sure some backwards compatability will still be enabled
- Depending on the objective of your testing, I would imagine you could still achieve alot with the alfa
Sure some guys that do this on a regular basis can comment on their kit, and future plans.
