The Open View says that God does not know the future - that it is "open" to Him, as well as to humanity, and that He is relegated to responding to events intelligently, rather than that God superintends events to a foreordained conclusion.
A lot of what you say throughout your post, I agree with whole-heartedly. When it comes to what God does and doesn't know, there seems to be aspects of scripture that don't yet reconcile with our current understanding of God being an all knowing God. There are definite references of where God has given people prophecies of what He will do and what He plans to accomplish at different points in human history. Then there are prophecies that seem to be more choices that He is giving us. If we make one choice, He will take one corse of action, while if we make another choice, He will take another. One example of this is in the book of Jonah and how because the people of Nineveh repented, God decided not to destroy them. It is in references like this, where God portrays Himself as changing His mind, that tells me that our understanding of God is still too lacking to nail down who exactly He is and how He acts.
I brought up the possibility that the members of the Trinity may see time differently. One possibility is that God does know everything, but decided to lock a lot of the details away from not only us, but also the Son and the Holy Spirit. That would help explain references about how neither the day or the hour are known by any but the Father. It also helps to explain how the Holy Spirit seems to guide us according to the choices that we make, while working to bring our choices into alignment with the words of prophecy that God has given us.
When I look at each the different views, I can see how each one stems from important truths about Himself that God was trying to show humanity. I know that none of them have a totally accurate picture of how things truly are, but instead each can help us take a step further towards that understanding. The question that we should be asking isn't which theological standpoint is correct, but instead what He would have us learn from each of them and how to take those individual truths and piece them together to form a more accurate understanding of His truth.
