You clearly don't understand how a sport gets into the Olympics program. A sport has to be practiced "world wide" at 75 countries with formal governing bodies and receive at least half of the IOC member's vote to get in(It used to be 2/3). China has done a poor job of popularizing Wushu around the world, so it will stay a China-only sport, just like the American Football.
Judo and Taekwondo has gone an extra-length to "dumb-down" their sports and make them easy enough for foreigners, so that there are many European champions and one of the most celebrated US Olympic competitor is a Taekwondo athlete. Wushu by comparison is simply too complex for foreigners, so no non-Chinese takers.
Karate may make it into the Olympics in the next 10 years, Wushu will probably not in your life time. Muay Thai has a better chance than Wushu.
