The engines are too far apart to have all revesers.

All four-engined jet aircraft have had reversers, Boeing 707, 747, DC-8, VC10, Tu-144, Concorde, Tu-104, Convair 880/900, Airbus A340, Lockheed Jetstar, An-124, C-5, C-17, YC-15, An-225 (6 engines), all have ha reversers, maybe some didn't, but for a large aircraft such as the A380, it seems all teh more logical to have that extra stopping power. And no, the engines aren't too far apart, the spacing between them is almost on-par (by scale) to the A340, and the 707 had them farther apartat its scale. Yeah, they say that its too heavy, whatever, it makes sense that you should, it could stop much shorter.
