That's what I thought - it's all weasel words, saying something because saying nothing is worse, but there is no certainty that Sky will be broadcasting the SPL next season, or that the current deal will be maintained without Rangers presence. Until somebody with clout at Sky comes out and says it/issues a statement confirming it ("it" being the current deal), it's all assumptions, adding 2+2 and getting 5, and reading between the lines. And there's nothing between the lines but blank paper.
ETA: I see people have already answered this - I'm still not convinced!
