I think that's a huge stretch.
This year, BotCon is releasing over a dozen toys that are all homages to something or other - mostly G1. And people are whinging that it's the worst BotCon ever for exclusives. Compare it to:
1995 - only one exclusive. Not a homage.
1996 - only one exclusive. Not a homage.
1997 - only two exclusives. Not homages.
1998 - only two exclusives. Not homages.
1999 - only two exclusives. Not homages.
2001 - only four exclusives. One homage.
Would they really prefer one to four non-homage toys than what they have this year?
This year I think we have:
Shattered Glass Tracks - Geewun/Diaclone homage.
Shattered Glass Soundwave - Geewun/Music Label homage.
Shattered Glass Longarm - Geewun/Animated/Binaltech homage.
Shattered Glass Junkions - Geewun homage.
Gigatron - G1 Homage.
Metalhawk - G1 Homage.
Octopunch - G1 Homage.
Spinister - G1 Homage.
Kick Off - G1 Homage.
Shattered Glass Darkmount - G1 Homage.
Shattered Glass Ultra Magnus - G2/Diaclone homage.
Shattered Glass Treadshot - Universe homage.
Shattered Glass G2 Optimus Prime G2/Shattered Glass homage.
People just like whining.
