Generating so many toys each year means they can run out of ideas fast. Remember the Beast Era BotCons which led into the Wreckers.... they had a story that spread over five years with a dozen toys (less than FunPub produce in one year).

1999 was the first chapter, with Sandstorm and Windrazor.
2000 followed up with a climactic battle with Unicron, featuring Shocaract and Apelinq
2001 was then the bridge between the Beast Wars and the Wreckers, with Tigatron and Arcee.
2002 set up the new Wreckers team, with Cyclonus and Cat-Scan.
2003 continued the Wreckers story, with ShadowStriker, Roulette, Sideswipe and Sunstreaker.


The main problem with FunPub is that they used their GIJoe format on their Transformers venture, which meant prioritising a lot of toys as the backbone of the Convention, rather than it being the souvenirs... But that's what happens when you have a convention of one fandom, run by fans of another fandom that has a significantly different demographic, focus and demands.
Some of their better years could have been chapters over 3 or 4 years, with 3 or 4 toys each year (two with the pre-registration, and one or two at the show). But it's a business after all, and I think they've got a bit too drunk on the massive amount of money the Transformers franchise is earning them after years of earning a lot less from just the GIJoe club (I was looking at their latest GIJoe convention photos, and it is a tenth of the size of BotCon).
