Well the Supergirl trailers already state in huge letters "From the Producer of Flash and Arrow", so clearly CBS can't be too worried about promoting or acknowledging shows on another network.
Sure, but that's just publicity, to get viewers to tune in. It's a different matter from a crossover, which would require a sharing of creative control and be a much bigger step for a network's executives to take.
Given everything else we have heard on the crossover front from multiple people, I honestly believe that people outside the situation are completely misreading Berlanti and Tassler's comments - all of which read almost word-for-word identical - to mean that crossover is entirely OFF-THE-TABLE.
Time will tell, though.
That's not the point. As with most things in life, this isn't a choice between binary extremes, but a matter of where things fall on the probability spectrum. Yes, of course, the probability of a crossover is above zero, but that doesn't mean it's anywhere near 100 percent. As I said, Berlanti's comment indicates that a lot would have to happen in order to convince all the decision makers to even
think about saying yes. So the probability of it happening is pretty low, and we'd be foolish to assume it will happen. It could happen, obviously, but that doesn't mean we should get our hopes up.
Just saying "It's not impossible" is meaningless. It's not impossible that we could be contacted by aliens tomorrow, but that doesn't mean you could safely bet money on it. It's not impossible that you could win the lottery, but it's overwhelmingly likely that you won't. Possible/impossible is too vague and trivial a standard to be worth talking about.
Probability is what's important. And the probability here, given what we know, is a long way from a lead-pipe cinch. Better odds than winning the lottery -- after all, what isn't? -- but still unlikely.
One of them could even theoretically change networks, right?
That seems unlikely. As Berlanti says in the
Variety article,
Supergirl couldn't be done on The CW because they couldn't give it nearly the budget that CBS can.
Is a crossover really so important that it's become the only thing we're talking about? Frankly I can see why CBS is discouraging one -- because all the focus on the CW shows is overshadowing
Supergirl itself. I can understand why they want it to stand on its own and establish its own name, its own voice.
I quite enjoy the interconnectedness of the CW shows, but that doesn't mean everything needs to be interconnected. There's value to shared continuity and there's value to standing apart and doing your own thing. If we can have Earth-1 and Earth-2, if we can have Marvel 616 and Ultimate, if we can have the MCU and the X-Men film universe, then we can survive having a CW DC universe and a CBS DC universe. And maybe in time we'll be glad they aren't the same. That's not impossible.
