One thing that will change, as per the latest town hall video, is that nodes with higher reputation will have more chance to host data from the network while unreliable nodes will not.
Hence why they have waitlist, so as long you have joined you will get access, however being able to store network data and earn rewards out of it will depend on how your node/s perform.
They are introducing reputation and based on that some nodes will earn rewards and some others will not be able to participate. I personally think this is for the best if we want Storj to be a success.
