I think you overlooked one key factor on Izzy: Katie Crown. She has clearly moved on from her time as Izzy. She's in Drivetime commercials, voicing characters in animated movies with Andy Sandberg etc. Unless they replace her or somehow get the money to do the Tara Strong/Twilight Sparkle deal I really don't see Izzy coming back.
