With respect, it's akin to saying "I expect that in another 200 years or so the fact that two plus two equals five will also seem 'obvious'".
It certainly isn't any different to a theist saying "I expect in 200 years that everybody will believe in god, because it will have been proved" or, indeed, an agnostic saying "I expect in 200 years that people still won't be sure". All you're doing is moving the same argument 200 years into the future, and the same problems remain.
Besides, in 200 years time when abiogenesis will supposedly seem obvious, who's to say that in 400 years time it won't? Who's to say that in 800 years, we won't have proved that the universe was created by an invisible pink unicorn?
