Those are definitely two very good points. For software I think the problem will really present itself once the Wii's succesor is released in late 2011 or early 2012. Nintendo has carried the system with first party titles, and once they stop releasing them the system sales will really collapse. The PS2 was still getting significant 3rd party releases long after PS3 released.
The second point about Nintendo's lack of presence in developing markets is also a very good one, and a point that is not brought up as often.
Still I think at this pint the Wii is almost certain to become the second best selling home console of all time, which would have been hard to predict happening after last gen and the Gamecube.
