So if the PSPGo was $250 and Sony says they sold what they expected (Like Nintendo said for GBA Micro) $300 for the first ever 3D portable system makes sense, and its much more likely to be $250 but $300 wouldnt be ridiculous.
Also, it is very, VERY, unlikely the 3DS will have 3G. For one thing, it isnt as necessary in the density of Japan's soon to be nationwide wifi, and it would also require Nintendo to partner with an American company, which given their choice of GPU, seems farfetched. Also, major American cities are stepping up their wifi plans in 2011-2012 right in the 3DS's infancy, and in most cities its going to start at public transportaion hubs, and in some places, on the buses and trains themselves. (On a side note I'm hoping that this transforms into a lot of (eventually cheap) wifi only devices so we dont have to be chained to cell phone contracts.) With so many people (especially suburbanites) having home wifi, and with wifi in places of public transportation, thats plenty of internet exposure for the 3DS to get updates/play online that 3G would not only be redundant but an unecessary cost.
And if Nintendo wants to implement anti-piracy through firmware updates I'm on board, and hopefully other companies will take the same approach instead of saddling us with new forms of DRM. I want to watch 3D movies and T.V on the 3DS, and Nintendo having strong (perhaps monthly) anti-piracy measures will encourage more distributors to get on board.
