I don't think I agree. For a start, unlike previous verions of HTML, version 5 is meant to be completely backward compatible. This was not the case for earlier versions. I think this time they might be closer to getting it right.

Even with that there were and are still inconsistencies in how it is implemented cross browser. The WC3 has stated that html5 is still a proposition. No clear rules have been carved in stone. It's only a draft

I feel confident most of the browser application developers will work towards more consistent support for all HTML5 features once they are finalised ( as you said, HTML5 is still just a work in progress - until early to mid 2012 I think).

Considering that browser vendors applied their own standards to previous incarnations and they are less bound to observe future standards it will mean more not less compatiblity issues.
...possibly, but there already seems to be more consistent support for HTML5 in all browsers than with previous versions. Maybe it will go in the other direction, and there will be fewer compatibility issues.
