Putting press conference with official PSP2 lineup and price annoucment a day or two before Nintendo releases 3DS would be smart move.
Especially if it's cheaper than 3DS.
Actually there's good chance Sony handheld will be cheaper. Nintendo will never accept minimal profit margin or slight loses on handheld. Sony especially if device is well protected against piracy and puts even more emphasis at DD titles could afford to sell at small lose.
