I think we pretty much are all doing the same as you....looking to see what will happen. For a lot of this stuff, there is not a lot of history to look back at to see how the future will be, so each new change brings a new set of dynamics. I think one reason Apple brought the 4th gen Apple out like this is because they are feeling pressure from the Droiders. With Samsung and a host of others always bringing out new products all through the year, it makes Apple look slow to respond and many start to question their ability to lead the pack. They say apple is not keeping up, is getting behind, because there are a lot of Droiders trying this and that to make themselves stand out. It's hard to be on the top of a pack like that. And as soon as Apple responds to the noise, they get dinged by folks for making their stuff obsolete. Honestly, there is nothing they can do to avoid POing someone.
I would say that the people who buy a Kindle Fire are, on the whole, not likely to be the same people to buy Apples or Samsung products. The Kindle is a pure consumption device, meant to drive people to spend money on
Amazon. Google tried to create a similar thing with the Nexus 7. Samsung makes more general purpose tablets, like their Galaxy Note 10.1, which has productivity features built in. Not designed to compete with Kindle. And neither is the Mini or the iPad 4. At least apple didn't try to compete on the low end and have left room for competition. In fact, on Monday Google is set to announce the Google Nexus 10, with a resolution higher than that of iPad.
