If Disney buys DC, I will bust through Kevin Fiege's wall like Kool-Aid Man to stop him from bringing in the rainbow of ring colors that has threatened at times to engulf the DCU in recent years.
How many ineffectual corps of Guardians of Oa types does one comic universe need? And what happens, in 15 years, when kids who grew up with Black Lanterns and Red Lanterns, etc., become comic book creators? Are we going to end up with Cyan Lanterns and Puce Lanterns and Mint Green Lanterns, as they strive to carve out more space on the color wheel? Just, no. This is the DC equivalent of the clone saga and symbiotes.
