Look at it this way:
It's late spring 2014. You have a plan of releasing browser mining in July, a "bank" interface by September and a course on cryptos on November; you state these goals clearly.
Now, there are hundreds of coins, assuming 10% have any competent devs, that's still tens.
As soon as you state those goals, some of the other coins notice those ideas, and implement them. Coin A makes a browser miner, coin B makes bank interface, coin C makes a crytpo course. All by July. Some other coins follow suit shortly.
Now it's July, and you have a browser miner, but other coins have that, some other coins have a bank interface, and some other has made a course.
By September you add a bank interface, and people say "meh, coin B has already had that for months". By November you write a course on cryptos, and people scream about a "ripoff of coin C's course".
Panda has always continued to make news of innovation, and this couldn't be possible without some kind of confidentiality. The end of the road is becoming the cryptocurrency for the masses, so the road is along these lines, I think.
Personally, I hope for the 100k merchants.
You are essentially making a case against the open source movement, against the core of all cryptocurrencies. Here is another way of looking at this.
All the coins that will survive must have a goal, and a road map leading towards it. If all you do is following and copying other's innovations, you won't survive long. The ones with a strong a vision, they already have their hands full, thus even if they want to steal something from us, they won't be able to, because they have to deliver what they have already promised. By the time they come around to copy our stuff, we would've already moved onto the next thing.
It's always better to be open and transparent than to hide cowardly in the dark.
