I couldn't have said it better man! (thumbs up)
When Jens released Indivision AGA all that bought it got it for a reason and that reason was VGA output with true AGA support and support for HighGFX modes. I don't think that anyone was let down about the speccs and features that Indy supported back then (end of 2008).
The fact that at some point SuperPlus was announced gave some thoughts and iirc Oliver had to develop a new firmware upgrade for SuperPlus to be supported by Indy @ some point.
Noone from Individual Computers announced that this was feature they were willing to make, so you can't really have any expectations for it from them. If they made such an upgrade then it would have been a nice free bonus for the already happy customers!!!
Ofc and since people's appetite strives for more features, Jens decided to add a bigger FPGA (possibly for Graffiti mode) plus DVI, etc.
Just be happy with what you have, and if you see more stuff, then either invest in new product or if you don't have funds, sell you Indivision and add some funds and get the new one... After all and following AppleHammer's example... that you would have done if you bought a new car that had a little better speccs than the one you got 3 years back...!
