Tennant isn't the 14th Doctor, he's the Disney Doctor and required by execs for RTD to boost ratings
After six episodes of the new Ncuti doctor and terrible ratings, they will have Tennant team up episodes, maybe even entire Tennant episodes to rescue a locked up 15th.
It's all about ratings and however much money Disney paid BBC for their joint venture.
Charlotte Moore, BBC's Chief Content Officer says: "We are thrilled to announce this exciting global partnership with Disney who are the perfect partners to bring this very British show to the rest of the world. Russell T Davies' vision for Doctor Who has always been out of this world and we are committed to ensuring that audiences across the globe get the opportunity to enjoy the Doctor's epic adventures with the scale and ambition that they deserve. Joining forces with Disney will elevate the show to even greater heights and reach new audiences so it's an extremely exciting time for fans in the UK and across the world."
It's not Tennant, it's RTD doing just nonsense for ratings.
Davies hint(s) about what season 15 will look like, suggesting we won't see the return of classic villains like the Daleks and Cybermen for a while. He said: "It's very new. Ncuti's new and Millie [Gibson] is new and it was new to us with Disney and the whole new era, as it were. So I didn't want to look... there are no Daleks, there are no Cybermen, I didn't want to look back too much."
"I would love for the Doctor to meet the Orisha, which were a set of gods in Nigerian mythology, and I think that he'd have a lovely old time."
Look at the casting..

Pure conjecture. Nothing in the quote substantiates your claim about Tennant returning. On the contrary, Davies has gone on record saying it's not happening.
They are already prepping season 2 without any notion of future ratings, so your argument is completely unmoored from reality.
"Blatantly lying" is ... a strong term for RTD dropping teasers and red herrings without spoiling the show ahead of time. It does however describe OP's claims pretty well.
Wow, why did they film it a year ahead of schedule? But more importantly, if the season hasn't aired yet, why do they think it received poor reception? Surely they're not basing this on behind-the-scenes "critics" whose opinions generally have no bearing on reality?
The christmas episode was pretty good. I could have done without all the singing parts, i hate musicals generally speaking. But as far as ncuti being a good doctor and RTD making a good episode goes. This was a good one.
You are entitled to your opinion, but maybe wait until it has all aired to form one, yeah?
If you are just making a prediction then at least provide some evidence instead of pure conjecture.
