On the surface it might look like there is competition, but there really isn't.
All other similar systems to Wagerr (that i see) propose to build themselves on top Ethereum. This won't work for several reasons including scaling issues, overhead of eth fees, and lack of control over the core network structure required for such an Oracle network to be efficient and cost effective.
Argree with your sentiment about adding more developers, except simply adding more people does not necessarily speed up a project (assuming they have the right people). Judging as an outsider viewing design decisions taken so far, I think they have good enough people.
We did this awhile back actually. Development was split into 2 main branches, one mainly focused on zerocoin/privacy/etc and the other focused on betting/oracles/etc.
We are currently in the process of bringing these two branches together, with further tests coming up soon. If all goes well, we could be betting in as little as a month or so. The team isn't giving any fixed deadlines though, but they have stated that reasonable time will be given before the upgrade.
We haven't forgotten about the monthly update either - so you can expect to see that shortly. For those who have been paying attention this month however, there won't be much they haven't already seen/heard.
When production stupid fucks? I don't care about your endless tests. We need production version!
