It would be nice but I can understand why they aren't, since it would likely delay the project. Plus I have a feeling that doing the project from the ground up with a new blockchain will allow them to do things that the steem blockchain just isn't ideal for. The userbase issue could definitely be a problem though as sports and the predictions arena is very niche. I wish them the best of luck though.
