Consider the following:
Gen 4 is actually ending and it will never be repeated.There's no way to do it again.
HOWEVER,Hasbro is not that idiot,they can't return to atrocities like gen 3,3.5 or anything because of gen 4.This last generation has made so much money to them and gave so much influence to the whole franchise that the direction they are taking will be related to a 2nd part of gen 4.
Gen 5 may be shit but they will not be commiting the same mistakes when they didn't make as much money as these years.Will gen 5 be better than gen 4?I honestly can't tell,but I doubt it will become the worst generation overnight like many dramatic faggots are doomsaying right now.
Enjoy these two years and get ready for what's to come.It
makes you appreciate more what we are receiving than shitting on it everytime.
