There are great features planned, all of which you will find in the roadmap. Two of my personal favorites which have the power to catapult XSPEC into the stratosphere and beyond are Stealth Staking and the mobile wallet with staking capability.

It's a common mistake to think an asset price will explode after something on the road map is finished but in the real world things don't work like that. In general, if something has been announced (i.e. public knowledge) it's already included in the price. The only way for it to rise would be if people were unaware of it being on the road map.
I agree expecting XSpec to explode as soon as stealth staking is released is a bit of wishful thinking, but the whole "price factored in" argument of economic markets doesn't really hold water when it's a little known asset. I agree with the comment that XSpec will be mentioned more often once the stealth staking is available, which should help the price quite a bit.
Also, because there's no guarantee that stealth staking will work (considering it's never been done before) there's risk involved in investing at this point and that risk is also factored in to the current price. Once the stealth staking is actually working, the risk is obviously lowered significantly which should increase the price.
