I think you may be reading too much into certain aspects of the advertisement ... I can't imagine why POET would release an ad if their intentions were simply to sell. Typically you would expect a company to release an ad with the intention of developing some brand/company recognition. I suppose it's all open to interpretation, though.

I'm not saying that it's impossible that there's a sale in the works (although I do believe it's unlikely), I simply don't think that this advertisement is really an indicator of that.
