Honestly, I'm disappointed, BUT I'm not surprised! I can't see them starting their own label till RBW owns MAMAMOO's trademark. My one and only problem with RBW is the lack of promoting. I'm sure other Moos feel the same way. I can't see that changing in the future, but I'm sure they have a good deal on their hands if they renewed their contracts.
Sadly, if we want OT4 comebacks, they need RBW.
Also, it's worth to mention the trademark for MAMAMOO will expire soon, too! In 2 years, basically! RBW can renew it for another 10 years, IF the girls let them do it! Maybe this is why they renewed their contracts. Let's be real, starting your own company is not easy, especially if you're not a mainstream artist or rich. After 10 years, RBW is the only company where they can do whatever they want. Other Moos mentioned, maybe there's a chance they can start their sub-label under RBW. That's also a good point.
Now that Wheein left TheL1VE, who knows, maybe she's coming back. I wouldn't be surprised, to be honest.
Anyway, tell me what you think, and here's a LONG thread about the trademark and how they can get the rights from RBW if they want to. It's not that easy, btw!
