VMware recently announced a new classification and pricing structure of their products. Starting April 2015, VMware will distinguish between vSphere products and Non-vSphere products. Non-vSphere products include vSphere with Operations Management and Acceleration Kits. As usual Vmware will also raise prices significantly within both categories. So if you think about buying new VMware products you should better hurry up.
By the way, Service and Subrscription as well as renewals won't be affected by the restructuring mentioned above.
Update/clarification 02/12/2015: VMware WON'T lift list prices of their products. They simply will lower the discount channel partners will get for new projects so for the end user it will have the same result.
