Rumors have been floating around that Metroid Other M and Sin and Punishment 2 have been delayed. Below is from an anonymous source on Neogaf.

Just got an official email from work about two of Nintendo’s biggest profile games of the year, Metroid: Other M and Sin & Punishment 2 being delayed. Metroid: Other M has changed from being released on 6/27 to TBD. Sin and Punishment 2 has changed from being released on 6/6 to 6/27

I would normally just take this with a grain of salt but Best Buy and Wal-Mart are showing an August release for Metroid and confirming the June 27th release for Sin and Punishment 2.
