The GT75VR has the better keyboard (mechanical and per key RGB lihgting), the much better screen (did people miss that it's 94% NTSC and HDR equipped?), and may even have better thermals. It makes no sense to buy a GT73 right now, before finding out the price and release date for its replacement. The GT75 very well may launch at the same price the GT73 did. That would make it a no-brainer.
