I think DSAT/Freesat will still be present for at least the next five years at least. The challenge currently is providing Internet (30MB+) for rural areas. Openreach's work turning off the copper network will probably help towards this. Even if those premises only get FTTC it'll still be an improvement, and help support TV via ISP.

I'm inclined to believe DTT/Freeview has a longer life expectancy. The barrier here will be that older TVs do not support receiving TV via the Internet, and many don't have built in WiFi support. Even if you can add a Roku stick into the HDMI port you may find (as I did) that the TVs USB port power is insufficient. Many people can't afford to replace their TVs within a year or two.

Therefore in order to replace Freeview manufacturers need to ensure all new TVs are capable of receiving tv via Internet now, and have WiFi built in. This will help to future-proof them, for serval years time when more people have naturally replaced their TVs.

I do however see Freeview changing over the next 5 years. We already have Freeview Play, which is used to provide catchup TV services, and I can see that side of it increasing. I wouldn't be surprised if the BBC's traditional red button stream closes soon, with iPlayer streams being used instead.

We've recently had the announcement of Bauer Media removing their radio stations from Freeview. I wonder if BBC might follow and remove their radio stations, citing the Sounds app being available. I also can't see many of the +1 channels remaining.

Then there's the possible migration to DVB-T to DVB-T2. This would at least remove some HD/SD duplications, and perhaps allow for a few more HD channels. There might be a case in the short-term to retain one DVB-T multiplex to provide some legacy PSB channels for older TVs. Presumably they could also offer upgrade support for those affected, as per the recent satellite changes.
