Buy VMWare Fusion 7 now?

Hello!

i bought a Mac and want to use a VM now. I thought about buying Fusion but i'm not sure if its worth because i think this year will come a new OS X and Windows 10 - i want to use both (at least OS X).

I dont want to buy a upgrade in some months just bcs of a new OS X. Is Fusion 7 my right choice? Will it get updates for the new OS X?

Thanks!
