Getting worried Panda is going the Dogecoin route: there's a great community, lots of potential but no innovation. (vague promises re "great things" don't count ...). Other coins have anon, encrypted SMS, video, telephony, naked cam girls (not ideal for Panda but you get the point) etc. One coin is based on the price of urea ( a kind of fertilizer). Sounds silly but the $2.19 valuation this morning for that coin is deadly serious. Glad I took a leap of faith and got some of those cheap and didn't listen to my BS detector. Another guy is basing a coin around the sale of hard apple cider. Unique idea; no interest/buzz yet but he's thinking and trying to carve out a niche.
I like Panda. As an investor this is bad, it is supposed to be only about ROI, money, etc. Getting accepted by zoos is wonderful. I'm not putting that down. But it also won't keep the value from heading back down to 1 satoshi. The devs really need to either release something and/or show a definite road-map re their plans. Otherwise this coin will gradually fade away.
You have to note that the devs themselves hold PND and also want to improve the coin as much as we do. I'm sure they have a reason for not wanting to give out information (mainly to prevent stuff getting copied, which is really common since everything is open source).
The most important reason that they are so careful about the control of information is they don't want the price to suddenly skyrocket because the news of a major release got leaked. If a coin is going to be around for the long term and be useful as a currency it needs to build its value slowly upon a strong base of buy orders to ensure stability.
