WWE has an NXT brand in North America & the United Kingdom and very well could be working on developing another one in the very near future.
Dave Meltzer reported in the latest issue of the Wrestling Observer Newsletter that WWE could be gearing up to have an NXT brand in Germany. The belief is that the upcoming tryout in the country is related to the idea of launching an NXT Germany brand. The plan, if it ever comes to fruition, would be to associate NXT Germany with wXw in the same way that Progress Wrestling has a relationship with NXT UK.
Triple H has mentioned in several interviews that the plan is to eventually grow NXT into a global brand with international versions in various countries.
