as you probably already know, Storm is answering stuff from time to time in the closed section of Russian forums. Here’s what he said about the test 9.9:
大家也许都知道，Storm一直在毛子的封闭板块中回答各种问题。以下是他对9.9测试服的一些回答：

– the optimization in 9.9 is nice, go check it out: 10 to 30 percent performance increase on various configurations
9.9的优化不错，各位可以自行体验：在各种配置上都有10~30%的性能增强

– the FV215b HD model is apparently fake, it’s a photoshop of the HD Conqueror picture (confirmed it with WG, it’s a fake indeed)
那个FV215b的高清模型是假的，只是拿高清征服者的图片PS了一下而已（和WG那边确认过了，的确是假的）

– the HD E50, E50M and E75 HD models are delayed. The reason for this is that they are being outsourced to various companies and these outsourcers work with different speeds so all the release plans for specific vehicles got busted. The introduction of vehicles is now practically random, based simply on what HD models arrive first
E-50，E-50M和E-75的高清模型被推迟了，原因是因为这些模型都是外包给不同公司去做的，而外包公司的工作效率又各不相同，所以关于在特定时间推出特定车辆的计划全部都泡汤了。现在高清车辆的实装顺序几乎就是随机的，什么模型先做好就先加哪辆车
