Actually, couldn't you just do
mainprogram()
begin
  makemat(
    // code that loops x from 1 to 25 and y from 1 to 25 goes here
    return(0);
  ,25,25);
end;
if the code was short enough?

Hmm. Doesn't work for me using Firefox 26.0 on Arch Linux. Do you have to wait a while before the video starts?

2064 seems a bit early for a deadline; remember that calculator projects never truly die.

The Palm Pre did this too (way before Apple; it's like app cards).

How long do you expect before the video is posted?

Or just something like EXPORT +[varname] for saved vars if they don't want to make saving over compilation default.

Feature Requestions:
1. Will we be getting the «»'s back soon? I really like them for debugging and things. You already have a RPN→BASIC framework set up (I'd think, with working RPN in home and function symbolic view input ("'X' 2 *" to "'X*2'").
2. Will there ever be named vars like in the other HP calculators (with nice menus and stuff)? You could make it an option on the last page of Home settings.
3. Is calc-to-calc IO planned or scrapped? You say to ignore it in the packaging, but you do have it implemented a bit...
4. Will we see built in 3D geometry? The CAS produces commands for it when you run the example for plotparam.
Bugs:
1. Help > Main says "This is the online help system for your HP Prime." The help is repeatedly referred to as such elsewhere. (Also, if it says that, where can we find the help online? )
2. General crashiness when using menus a lot without closing it. Try going into CAS and doing Toolbox > CAS > Polynomial and pressing left-right repeatedly; it gives a crash pretty handily.
3. Geometry Symb's default GA is undef, you can keep it that way if you hit cancel. Attempts to set it from CAS have no effect upon repeated sets.
4. Advanced Geometry Symb: Tapping upon a non-null V var doesn't show the same menu as if you pressed Edit.
5. SIN(π)≠0. I get the exact same number on my 35s. I don't know if you can fix it, but it would be nice.
6. User Keyboard help page does not specify how to set User keys. It looks useful, but I'm lost.
