That's a stupid question if it's standards compliant then web development will be browser neutral, the whole point is to not develop for a certain browser.
I think the question is not whether we will be swayed to develop for a particular browser, but rather (as a commmenter stated earlier) it will end the trend of developing "in Firefox, Chrome, and Safari first, then switch to IE 7,8,9,... to "see how broken it is"
