The body of the A77II is IDENTICAL to that of the A77; both are Magnesium Alloy and plastic in exactly the same places.
And while GPS is gone in both the mk models of the top end SLT cameras, in both cases it has been replaced by greater connectivity (WiFi and NFC) and in the case of the 99mkII, location via GPS can be obtained through linkage with a smartphone. A net gain for that model and a tradeoff for the 77mkII.
And as a long time user of the original A77, I can tell you that they A77mkII AF module is MORE than enough justification for purchasing the new camera. It is a completely different experience, and more in line with professional cameras than anything Sony had ever stuck in one of their offerings.
Additionally, the ability to download images quickly via WiFi is another advance, the value of which is completely underestimated by people UNTIL they use it.
Also, you don't need the AF illumination light because the 77mkII is several stops MORE sensitive in low light than the 77 is. AND in the event that you DO need an AF assist, the pop-up flash serves that purpose.
I don't own the A99mkII YET. I'm one of those people who has to save to buy gear, and with retirement just across the street and two granddaughters college education to pay for, toys are way down on the list of priorities. But when I DO buy one before the end of 2017, I suspect that it will be a HUGE advance over the A99.
I gotta say this again; we are not quite grasping the true cause and effect relationship between increased costs for photography related products and the reasons for those increases.
Manufacturers are charging more because the market is shrinking. That was evident in the video... and when fewer people buy your product, you HAVE to charge more just to make the same profit... or for that matter, you have to charge more just to stay in business.
Additionally, YOU lot there in the UK are paying more BECAUSE of a little vote the majority made last year that will cause EVERYTHING to cost more.
As to entry models... Sony is selling what the market will support. Right now they REALIZE that they can only offer 3 SLT models. They do offer bridge cameras for entry purposes to both their A mount and E mount line ups.
So far they are still making money... something that can NOT be said for other companies with more comprehensive ranges of cameras.
