My comment was mostly about focus. Nokia has one single problem: they need to build phones people actually want. They have to develop the phones people will want in 2012 right now so they are shipping and working very well (Apple's iPhone has somewhat raised expectations) in 2012.
Elop used the burning platform metaphor. If it's burning, the sole focus of the whole company should be on building a new one.
A new corporate font is not a competitive advantage, will not make whatever new platform they build with WP7 more attractive to end users and is, thus, a waste of time and resources. The cost of having a font designed is tiny when compared to the cost of reformulating the visual identity of the company, something that's bound to happen.
Marketing should worry about selling as many current phones as possible and nothing else.
I can't see how a new corporate font fits in this panorama.
