These are the PSP games I am most looking forward to:

• Syphon Filter
• Gran Turismo 4
  
• Splinter Cell Essentials
• Tomb Raider Legends
• Brothers in Arms
• Daxter
  

These are all scheduled for Q1 according to Gamespot, I guess we'll see. I will have to get a Nintendo DS as well, just for Mario and Luigi 2 and the upcoming portable Resident Evil :-)
