Yep, is does make sense. And unfortunately this seems to be a known problem as all their keyboard were exchanged without a problem.
However, I know 6 people who own a rMB. All of them had the keyboard exchanged at least once, 2 people even have the 3rd keyboard and one unlucky guy has the 4th keyboard.
In the end, it's just a matter of time until the keys get stuck after the warranty period and that's the point where it gets not only annoying, but also expensive.
Apple even made a guide on how to clean this keyboard with canned air, but that didn't seem to help for any rMB owners I know.
If they just put the same keyboard in the new rMBP, I'm not buying it, no matter how good the rest of it is.
