I bet for Airtel to beat Safcom, then they'll have to beat them at M-Pesa to surely get the numbers first. Later they can enter easily into data. Else they should have a strategy to concentrate on voice, voice, voice. Betting on the idiot CEO after MJ's departure might not be an ideal strategy to beat them.
I also bet Airtel apart from poaching MJ should devise innovation strategies and maybe poach heavily from Safcom's technical and management teams.
Now looking at all these possible scenarios, Vodacom and GoK need to devise counter strategies these could look like:
1. Consolidate M-pesa - maybe the M-Kesho way
2. Poach MJ's replacement from BBK, KCB, KQ.
3. Consolidate dominance in data - the Opra Mini style.
4. Delay changes to number portability - the same way as with Communications Act 2010.
5. Employ more anthropologists
In MHO, this is no mean tusk for Airtel as for Safcom survival, it survives in the short term and in the long term its all upto its future strategies.
