DRosencraft, you have some mistaken information. The Challenge Event that just concluded featured the following rewards (not including items that can be obtained through other means in the game): In this list, #1-5 were given away during the first Challenge Event in August. However, #6-10 were given away for the very first time in this November event.
 * 1) Lancer Squadron emblem
 * 2) Cocoon Squadron emblem
 * 3) Beast Squadron emblem
 * 4) Albireo Squadron emblem
 * 5) Rot Team skin for Typhoon
 * 6) F-35B Lightning II JASDF skin
 * 7) EA-18G Growler skin
 * 8) Su-35 Super Flanker skin
 * 9) Grun Team skin for F/A-18F Super Hornet
 * 10) Grun Team emblem

But otherwise, you're correct. The clause stating "Rewards may be obtainable in the future" has been added to all tournaments and special challenges since at least Update 2.00 in October. I agree that this is more of a safeguard than anything else, and that I don't think they know exactly how they're going to do it.

There is a theory going around that Bandai Namco has a yearly plan for Infinity, where, when May 2015 hits, the events will repeat themselves at the same times as when they happened during the game's first year, essentially making the game infinite for any player who joins whenever. There is also a second theory that all of the special aircraft and such will become paid DLC and the events will not repeat.

In any case, we have no idea what their plans are for providing the rewards in the future.
