BBC signs deal for the 2014/6/8/20 Olympics

Well the BBC bring back the axed channel/red button feeds for the sport coverage in the summer?

If you mean the DVB-T/S feeds - then unlikely. "Red Button" is likely to transition to IPTV delivery - as has begun with iPlayer on Freesat / Freeview HD boxes. So the Red Button may well deliver lots of feeds - just not using broadcast RF spectrum.
