If I purchase the current MoP Guides, will I be able to get 90-100 when it is release

[LoadedCamera]

I have been a loyal customer for a very long time and have recently started playing WoW again and am interested in purchasing the MoP guides, but with WoD just around the corner, I was curious if I would be able to get an update at that time for the next x-pac guides? Or should I just wait for WoD to release and get the guides then?

Thanks in advance

Right now guide purchases do not come with WoD expansion upgrades.
