To be clear, Apple is not in rush for a new MacBook Pro. Why? It's because most of the buyer's never heard of Skylake, Thunderbolt 3 etc. They are not as much interested in specs then we are. My Girlfriend never heard of Broadwell oder Haswell but maybe your Girlfriend does. She buys it, uses it and thats all.
The Phones are having much more attention for the majority, they are more comparable. Maybe like a fashion product. Not to forget, the revenue is much much larger.
This is a valid point, however, ... the MBP is for professional users. Most professional users are savvy on their technology - this is what made the MBP so sought after in the first place. Thus, a majority of those who are waiting for a refresh/update/spec bump (like myself) are professionals. The number of 'consumers' who look at buying a MBP would be negligible. Most 'consumers' (who wouldn't know Skylake from their bunghole) would be happy/happier with the cheaper, lighter Airs or MacBooks. They would neither want or need the extra power of the MBP and most likely wouldn't want to pay the extra dosh for one.
The majority of Windows based laptops sold are mediocre performers at the cheap or middling price point. All the uber expensive machines are either work stations (for the professionals who don't like OS X) or Gaming machines (for those who wouldn't bother with a Mac because they aren't great for gaming). It was, in fact, that MBP that defined the 'professional laptop' genre of computing. To see Apple letting it languish is both disappointing and heart breaking. Steve Jobs may not have been the most wonderful human being on the planet, but he did have a vision... a vision that has gone down the toilet since his passing. (Not to say that his vision was always right... I mean, 3.7" screens on mobiles is ridiculous!)
I have around a month and a half up my sleeve until I need to spend my money (in order to claim it on my tax). If Apple do a spec bump to Skylake (heck, even Broadwell would do) in April/May, then I will buy one. If they wait til June and WWDC, that means I won't be able to get my hands on one until July, which is too late... I will have to sort something else out. I do need a new laptop - the battery in my Late 2011 MBP doesn't go enough distance anymore, and it is pointless just replacing the battery when I can afford a new laptop, with much newer CPUs.
I see my options as:
1. Buy a spec-bumped rMBP in April/May
2. Buy the cheapest MBA in early April then sell it and buy the redesigned/refreshed rMBP in June/July
3. Buy a Windows based machine such as the Razer Blade, or Dell (yuck!) XPS 15.
