And knowing Apple, that major redesign will be considerably gimped in many ways, like having the horrible new ultra-flat keyboard, lacking ports and a dedicated GPU, and probably will be plagued with general problems until the second or third revision will be released.
If a user considers such new features as gimped, they have probably bought their last Mac...further revisions won't bring back old ports or old keyboards.
The laptop range is a mess right now. The new MacBook clearly shows the future direction for Apple. The Airs (if they survive) and MBPs are ready to adopt MacBook design and technology advances, but are waiting for the next generation of processors.
I think the new 15" MBPs are mightily impressive machines, but they have fundamentally ageing processors. If leaks showing Skylake H processors coming in September 2015 are right, the 15" MBPs will skip Broadwell and get a radical overhaul in terms of form factor and technology later this year.
I bought a 2007 MBP a few months before Apple released the first unibody machines. Love my MBP, but wish I had held on for a few months and bought into the design ethic and technology that unibody brought. My 2007 MBP has lasted really well in isolation, but it aged very quickly and belonged to a design ethic that later models didn't share.
I, for one, want the new design, new keyboard, new processors, new ports, new controllers, etc that Skylake will usher in. I don't want a machine in 2015 that is wedded to technology predominantly from 2012. I might have a few more months living in the past with my old MBP (I have other Macs as well), but by waiting, I won't be living in the past for years with an old Haswell machine when I have a Skylake machine in the future. People buying Haswell machines now will have years in the past in comparison with my few months.
But completely accept other people have different opinions and needs, and I totally respect them.
