The article is mere speculation very similar to your own and nothing is even confirmed by Seven. Indeed, some quotes from the very article you refer to:

Yet Unwired's customer base has stagnated since the takeover and its visibility has dwindled, with Seven seemingly ignoring its subsidiary (of Seven's 100-page annual report, only one paragraph was devoted to Unwired).

While Seven's 50¢-a-share takeover offer valued Unwired at $169 million, the broadcaster would have known that the eventual takeover cost would end up closer to $500 million.

Unwired's existing pre-WiMAX network covers Sydney and only a third of Melbourne. Seven last year estimated the cost of upgrading Sydney, expanding Melbourne and building networks in Brisbane, Perth and Adelaide would be $200 million.

That estimate seems overly conservative as there is no guarantee that construction will begin this year, and that Unwired wants to extend to Geelong, Newcastle, the NSW central coast and the south of Perth.

Nevertheless, most analysts believe Unwired's delay in building its network has given the telcos an insurmountable lead in the wireless broadband market.

Telsyte research director Warren Chaisatien laments that Australia is "three to five years" behind Europe in offering such "triple-play" services, because those capable of doing so have not had the incentive to offer truly bundled internet, phone and TV packages.

Unwired chief executive David Spence, a long-time WiMAX evangelist, is coy about any plans for triple play.

But all this will depend on Spence convincing Stokes and the Seven board not to be cowed by the economic crisis, and to commit the hundreds of millions of dollars needed to build the network.

So, at best the triple play option is an option available to Seven but in summary, Seven need to make firm announcements to the market and commit to a project that some say will cost north of $400M to implement.

I would say that landline broadband delivered VOIP services are pretty safe from any WIMAX competition for at least the next 3 years.

And again, Seven only owns 58% of Engin, surely the vast focus for revenue and profit will be Unwired which it owns 100%.

So, PP, are you advising people to buy ENG shares on the strength of this Melbourne Age article? Or what are you advising exactly?
