According to HK-Kicks ~ The MLK & MPLS will supposedly drop April 6th... not June. Pairs will be limited. The MPLS will be available at Nike Basketball (inMong Kok) and Nike Flagship (in Tsim Sha Tsui)... the MLK's will only be available at Nike Basketball. Given how limtied the release is, a lucky draw willlikely be used.
"Nike WK" is actually "Nike Basketball"... WK stands for Wan Kee, which is the company that has the Nike Basketball account. They get a lotof the exclusives and PEs... similar to Foot Locker's HOH getting special releases. WK has a chain of sneaker retail shops, much like Foot Locker.
The only problem with Nike Basketball (Wan Kee) was that in the past, some of their 'lucky draw's' have been 'allegedly' shady. Iwasn't there to witness this, but according to some HK-Kicks members, some of the lucky draw people had two tickets instead of one. Some shady businesswithin their staff. Nike Flagship (official Nike shop) never had this problem.
