I think $229.99 would be a good launch price for the portable. It's just a small step away from the standard $199.99 that people already pay for a 3DS, and if push comes to shove, you should be able to drop to $199.99 after 8-9 months if you really need to anyway.
The extra $30 gives you a lot of breathing room in terms of the type of chipset, RAM, etc. you can use though.
Just make sure you have a good launch lineup. Mario Galaxy 3 (or whatever its equivalent is) should already be earmarked for launch and be in development right now.
