Well, things just became a bit harder for a potential DS series to be picked up by the CW -
CW Renews Riverdale, Batwoman, Roswell, Black Lightning Plus 9 Others- all because of a possible writers' strike come spring. And a strike of that sort, if it were to happen and it were to go on for an extended period, as the 2007/2008 strike did, would most probably push back the debuts of any new series the CW (and any other network) announces in May.
Though there still are a few things to keep in mind:
Even with all these early renewals, presumably, as I mentioned before, the CW would still need replacement shows for
Supernatural,
Arrow and
The 100. And
Whose Line Is It Anyway,
Burden of Truth,
Pandora,
Penn & Teller: Fool Us and
The Outpost are not among the early renewals so, if any of those series are canceled, that would mean that the CW could possibly have even more openings for new series come May. But that remains to be seen. But even with all that potential, more importantly, we don't even know if Mark Perry's DS script is even going to get a pilot order. If not, then the number of openings the CW might need to fill for next season would be moot so far as we're concerned...
The primary thing we need to do for the time being is remain hopeful that Mark Perry's script gets a pilot order...
