The only dominant players left in the marketplace are mostly Toei properties & Pokemon.
Recent Interview with VIZ Media Vice President Publishing Leyla Aker:

Long gone are the days where retailers would stock anime properties, and Saturday Cartoon Shows in general.
It's a tough market and it's going to be an uphill battle for Youkai Watch to receive any type of recognition - it's going to need a significant investment from Bandai Namco (most likely the master toy license) and I'm not sure they are willing without some kind of financial aid, either from Nintendo (publisher), or exposure, from kid-centered channels, which seem less likely with each passing year now that the CW Vortexx have dissolved (Yu-Gi-Oh! was on that channel) with only 4 major players left: Cartoon Network, Disney XD, Nickelodeon, and Nicktoons.
And like I mentioned earlier, the 4 channels above are switching more and more to internally developed content - I just don't know.
