Well i would say that concidering all the mergers and by outs that WB has been involved with lately that it's a good bet that they wouldn't waste money doing something half way. they will need to make some finacial gains to make up for what they have bought.
WB is in the business of makeing money, they see potential in RT. they see what ppl say about TF and i'm sure they are gonna try to avoid that mistake..
