My question about "(Valve Product) 3" was fairly swiftly closed and the rationale provided seems fairly senseless.
The actual close reason was the "not constructive...should solicit facts, references", which is precisely why I was asking the question in the first place; for some definitive, well-referenced facts. This is a question about a rumor, but seeking to turn it into a fact (either way) with the aid of references (a-la Skeptics.SE).
Comments seem to suggest that this is not answerable ("not a real question"), but there are many scenarios where it could be definitively proven and thus answered; an official forum post directly addressing it (similar to the one agent86 posted, but with additional context), or a Valve staffer directly emailing a reputable news organization. Such a source would obviate "Rumor + trolling community + we won't know with absolute certainty until E3 2012" as we would know that the "something with a three" was true (as much as that phrase can be stretched)
"Too localized" also seems out as this does apply to the internet at large, and the question itself can't be interpreted significantly differently in the future (leading to red herring Google results)
There's "off-topic" as the FAQ forbids "Speculation of the future of the industry and of upcoming releases", but again I'm explicitly trying to not be speculative and looking for some facts either way. Is it off-topic for less codified reasons?
