Version 4?

[Matt Foster]

I have long since procrastinated my migration to V3, as it's a radical change in functional behavior of objects, ie map.addOverlay(marker) vs marker.setMap(map).  And in contemplating the ambiguous impending doom of the version that makes sense to me, I'm wondering when the next release of the maps API can be expected.  Because at this point V3 has matured for a few years now and if I'm going to commit the effort to refactor, at this point, I'd rather go for the latest and greatest instead of upgrade to the freshly deprecated.

for the sake of discussion, I am suspecting v4 will have something to
do with mapsGL (currently available on maps.google.com for certain
browsers) when most browser can handle webgl.
