The winner is.... me? Technically, but really HaloOfTheSun!

I collected a gifted pokemon to make it 3,999 and Halo caught something in the ~4 or so seconds between checking to make sure I'm not #4000 and gifting, making him 3999 and me 4000 =| So he gets it :zwink:
Halo was offered any shiny as a reward, and went with the majestic Xerneas:

Gen5 Announcement
RMRKMon's Poké Authority has convened upon a decision to enable Gen5 pokemon when 8,000 pokemon have been caught! This is double what we have now, though our catch rate is accelerating. Our best guess puts 8k being reached at maybe 8-10 weeks. Good luck!
