Tardis had nothing to do with it, he went to get the job back after Moffat and Chibnall had their time with it.
Some article claimed RTD2 would be "radically different". Whether or not it actually is... the teasers can easily be misdirecting viewers as well.I wouldn't think too much into anything in any single direction. Unless they are "taking the piss" out of viewers, since the bit with the voting posters is as much anti-Robinson as it is pro-Saxon. Both were "meh" anyway. And, "obvs", the two lampposts so close together must surely be it's gonna be a parallel world adventure too.
