That happened to me kinda. I bought Diamond/ Pearl. Played the heck out of Diamond. When Platinum came out, I played it but didn't even finish. I put it down and didn't pick it back up...And then....there's this blurriness of time that I cannot for the life of remember. I guess I had fallen out of Pokemon...maybe it was my Pirates of the Caribbean obsession phase...well, for whatever reason, I got really distracted from Pokemon. I never missed any events even when I wasn't obsessing over Pokemon... except for one...I totally missed the Shaymin Toys R US event-which my sister went and got without even telling me!! What the heck............. =(
