At least some changes are being made. I think their original plan has backfired on them; in that you would have to pay a hefty monthly price. Notice that they killed off new developers when they stopped issuing API keys. Now they are going to offer something to developers and to the people who provide the data. This change tells me that the original plan wasn't well received at all.
Since there are no details, anything is just speculation. I'm guessing they're going to try to keep this as quiet (therefore the "we'll contact you") as possible to reduce the outrage, but that nothing is really going to change. IBM isn't interested in consumers directly.
