I don't think that Kim is holding information on purpose (at least I hope not). I think he has his hands tied because of all the players involved in this Company. I think R&D is still going on and there seem to be a few NDAs or CAs that are not helping in favour of greater communications. Though I must admit that some PRs were pretty insignificant and even had negative impacts on the PPS.
I still hope to see some real progress this year (and the positive effect on the PPS), actually, in the next four months or so, if it's sooner I'll be pleasantly surprised.
