I've been needing to use my rMBP 13 more and more but only need it in the house. To this effect, I think I would be better served going for a rMBP 15 for the extra horsepower and larger screen. Does anyone have any thoughts on what a new MBP 15 announced in June may improve over the current 2014 model? I'm looking to pick up a bargain on the 2014 model with GT750M graphics but will hold off if the improvement will be substantial? I guess this is an unusual scenario because the current gen has been used for two models now so the Broadwell update may bring a bigger boost. My uses will be mostly RAW image editing, iMovie editing (possibly Final Cut Pro X) and maybe some occasional gaming (X-Plane or Aerofly FS flight sims) if the graphics are up to it.
