Actually, I'd put the game/app devs at blame tbh. There's little reason to add extra OGL support in drivers when there's no software - there are many other issues that they should be fixing first. (although its probably not too complex to add the supported extra features, its all software anyway). The devs can always include backwards compatibility (like DX) so even if you dont have 4.3 support, the game/app will just run with the newer features disabled. There'll always be an argument to support each side though, its kinda chicken & egg.
