Is this WiMAX card destined for MacBooks?

Not to scale.
Intel doesn’t want you to know, but the FCC made this public anyway. That company they call Chipzilla is releasing a new Wi-fi/WiMAX combo card with the same form factor as the one in current MacBooks — you know, the ones due for a refresh soon. Coincidence?

At the moment, these cards have no way of functioning in OSX because there are no compatible drivers. That can be fixed quickly by Apple and Intel, and my guess is that a driver release is how we’ll find out whether the new MacBooks will have ’em.
