@Mrstickball: As i said, it's the growth that makes the devs interested in the platform. Once it's not growing as it currently is and the market becomes oversupplied - then what?
Smartphones, and everything they are used for, is experiencing growth because they fit into a segment in multiple markets. What's happening is, that they grab their share of the markets but that's just about it. Next thing to happen is that the low-end phones grow in features so, that they start eating the smartphone market.
If the mobile phones gaming would have eaten portable consoles away, it already had happened years ago. And if you noticed, your reasoning why iPhone and Android would eat away Windows Mobile, Ovi and BB is the same why iPhone and Android won't eat away portable consoles.
