I doubt you'll see any new chips for either one. It's more a matter of buying a motherboard and cpu that you plan to use unless a pentium g3258/i3 with plans to upgrade to an i5/i7. Futureproofing is a myth.
For instance, lga1150. It supports haswell, haswell refresh, devil's canyon and broadwell. Then you have to move to a new socket. If you have a haswell i5/i7, there's no point in 'upgrading' to a haswell refresh/devil's canyon or to broadwell. There's no point in upgrading to skylake from one of those cpu's and it's on the next socket.
People with sandy bridge on lga1155 didn't bother upgrading to ivy bridge, haswell, haswell refresh, devil's canyon, broadwell - and are just now considering skylake. They skipped not only the next cpu for 1155, they skipped the entire lga1150 socket and all of its cpu's and moved to skylake (lga 1151). There's just no need to upgrade a cpu every year or two if you're looking at i5 or i7. They tend to remain highly competitive for 4-5yrs.
