It looks like they're selling it earlier than Casio would allow them to do. This happens with games in my country. In some gaming stores, people sell games before the release date, but usually those employees are then fired :S

As I mentionned on Cemetech and on both IRC channels, For some reasons, it seems like the Casio Prizm is out already. The release timeframe of January 2011 is gone from their website and the calculator appears to be available on their online store at http://www.shopcasio.com/product/4063

At first I thought many Ebay sellers started selling it before the release date, but now I know why that many started selling them. Snake_X caught my attention because he mentions that a local store where he lives already sells them.

I guess that maybe they wanted to release it early to get a few additional sales for Christmas, but I hope it's not rushed either, because like TI, they're not known for bug-free OSes.

Ouch sorry to hear. I hope you can get some more money soon. And yeah it would be better to buy it in store. Much easier in case it's defective or something, although I wonder if all stores will carry them...

I don't go out too much, so I'm not sure if they're here yet. Haven't seen them in the ads in the newspaper, though.
I'll keep checking
On a somewhat related note, I think I'm going to wait before the (non)existence of an SDK is announced before I decide whether or not to buy one.

Hmm I hope they just mean they do not have it now and that they are not aware one may be available eventually. It would kinda suck if it didn't have one. It would be ironic, though, considering the calc already have flash app support in the first place (Maybe only Casio will make them?).

That said, SDK or not, this calc will still be more programmable than TI-Nspire BASIC. It has a getkey function, text commands and some drawing commands. Just as long as it's not incredibly slow.

Also maybe it will be hackable.

On a side note, it seems that Casiocalc.org has turned into an anti-game forum in the past year or so. Back in the days, it used to be both development and help, and now it seems most people are against calc games or think it's stupid to play games on calc. That said, I think Ashbad's comment was trollish, though, and I reported it to moderators (along with the response).

Oh well, if Casiocalc.org has turned into TI-Nspire Google Group/Univers TI-Nspire II, then we can easily start our own Casio Prizm dev community.

I guess someone will have to explore the Prizm and make some kind of SDK until the Casio one comes :S

Finding a way to run unsigned code might be tricky... Maybe as tricky as the Nspire.

Oh, those... Aren't they documented in the manual?
