This article has outdated information and AMD has already made an official statment that the 7000 series cards will support DX11.2: "The AMD Radeon™ HD 7000 series hardware architecture is fully DirectX® 11.2-capable when used with a driver that enables this feature. AMD is planning to enable DirectX 11.2 with a driver update in the Windows® 8.1 launch timeframe in October, when DirectX® 11.2 ships. Today, AMD is the only GPU manufacturer to offer fully-compatible DirectX 11.1 support, and the only manufacturer to support Tiled Resources Tier-2 within a shipping product stack.”
