Well, you have to understand that Academia is pretty cutthroat and there are just as many people who have a stake in disproving things like extraterrestrial life as do in proving it. Not to mention concerns by those in power about not wanting to jump at even clear evidence, spend a ton of money, and then find out that some kind of mistake was made. This is to say nothing of the social order, and how many belief structures would be literally decimated by the acceptance of life off of earth... sudden, radical change being bad.
That said, the bottom line is going to be when these scientists decide to take these rocks out "on the road" so to speak and show them off person-to-person with the electron microscopes. The debunker mentioned in this article (as part of the update) seems to mostly be attacking the sources (Fox News, websites, etc...) rather than the work itself, other than to say that he personally disputed the claims and had trouble making things out from the pictures.
I don't expect a lot to come of this any way it goes, to be honest it seems like the kind of thing that is going to be sat on if it is for real. Not so much because of any "X-files" like conspiricy full of creepy guys in black trying to cover up evidence, but because nobody will want to put it out in public until they are sure, and it will be being poked, prodded, dissected, and battled over by career academics for decades before anyone lets anything signifigant come of it.
That said, there is a lot of strange and creepy crap out there that it seems few people want to deal with, never mind society as a whole. This will probably just be added to the list.
