Dear Cristi
If I along with many debunkers of QM weirdness are right, Wheeler's delayed choice test being confirmed by experiment does not mean much. Here is a quick-and dirty explanation of how I see the scenario:
Forget point photons, wave collapse and all that. Einstein's 'photon' concept is the font of all the QM weirdness he himself railed against! Compton himself gave a wave explanation for his effect as Reiter explained on unquantum.net - all proving Planck's loading theory in which an atom releases light suddenly but absorbs it slowly until a threshold is reached and the (hv) quantum released.
In other words the light wave passes simultaneously through both slits and creates the wave interference pattern beyond them. In the famous faint-light case when the pattern emerges dot by dot on the long-exposed film the timing of the dot flashes in the film is an artifact of the sensing atoms individually and randomly reaching their energy threshold and has nothing to do with how the light went through the slits!
When the film is removed and two telescopes watch the slits no simultaneous sensing is recorded because of the energies involved. Reiter has shown how a single gamma ray is simultaneously recorded in two detectors.
I have touched on these issues in my 'Fix Physics' paper, and the scenario above plays out nicely in the universal node lattice of my Beautiful Universe theory.
These papers can be read on my website . I am now trying to simulate my theory to show how things like matter formation, gravity, quantum probability etc. all emerge locally linearly and causally. Big job small capability!
Best wishes
