if i had millions ($$$), i would have you make up a bunch of Mini2560, and 2560 DIP. ;)
DIP version probably won't come out.  64 pin DIP is the biggest package and those can be hard to insert or remove from breadboard.  Someone did come up with a PCB to DIP package for ATMega2560. 

2560 pro mini are common on eBay and usually under $20 shipped to most places.

Good point.

But does the Arduino team publish audited accounts so you can see what happened to your donation?

No. I gave them $25 as a part-down. I'm not paying for hopes, I paid on what I already have and updates since 2011.

Your sketch can sense ongoing process events in time.
Your sketch can make events to control it over time.

"2560 pro mini are common on eBay " with two row pins on each side, so you can't plug them into a solderless breadboard.  Mine was designed to go into a solderless breadboard.


Here it is with an FTDI Basic with short extension cable to a vertical header.  A right angle header could be used as well to have the FTDI Basic lay on the board. Other header types can be installed as well.

True but a small board with DIP form can act like a DIP. I would want at least 32KB external RAM and SD on-board on a 40-pin wide package and USB of course.

But compare to the newer Teensy 3.x boards with USB, SD and much RAM in the $30 range... I dunno if the 2560/61 can come in for significantly less. Maybe it doesn't have to, AVR pins are more robust/hobbyist friendly.

Anyhow I like the idea of a small board that can replace a DIP chip and add features, maybe hotrod the clock. Come to think, as long as the board it plugs in has USB, it don't have to!

I worked up this 1284 Logger as well.
1284P only has 16K SRAM, but I did fit in uSD card, you can out on different crystals.
MightyCore supports 16 or 20 MHz, and someplace there is 24 MHz support as well.
Or try 32 MHz.

Here it is with a Programmer connected and an FTDI Basic on a short extension cable
