Aargh, the pressure!
I'd say somewhere between now and when the universe ends. Roughly.
Serious answer: I only have one room at the moment, and i made it just for testing a particular game mechnanic, so it's still very early. (It loads pretty fast though.)
I'm aiming at releasing the public beta somewhere near the summer. (This year's, preferrably.)

At least that gives us an idea.
Seriously: That was a great map, I hope you release another one.
Absolute quality. The attention to detail on this map is awesome and I really like your style. It's got a very portal-but-not-portal feel to it which is great and original. Some puzzles are a tad overwhelming at first imo but after a short while of studying the level it becomes clear what you got to do. I did get a bit stuck on the ball puzzle but generally the difficulty is fair and moderate.
Classic map dude. Hope to see more in the future 
I noticed that too. I was reminded of the original Myst games when I was playing this. It was great.
yeah... Myst included more than only puzzles. It showed lots of detailed things moving etc. when you solved a puzzle, and to get to a puzzle, the surroundings where nice. Many times you also get the pretty surroundings being part of the puzzle.
Same as with this map. It's not 100% time puzzling your way out as in most other maps.
Again, thanks everyone for the great feedback! I notice that many people see parallels between my map and other games. I've heard of the Myst series and have seen screenshots of it, but never actually played it. That sounds like an interesting thing to check out.
BTW i'm making good progress on my next map. I was originally planning to give it a more authentic Portal look, but i may have to come back on that decision.

It was the pictures on the wall of the last room, the room where most people got stuck, that reminded me of Myst. They had picture clues like that in their games.
I thought the part where you walk over a bridge to the ball puzzle looked like the Myst series... those pillars etc. Also at the end, when the pieces of the ceiling come together so you can place a portal on them, giving you just the thing you needed to complete the puzzle on a golden platter.
But yeah, keep your maps in the style you've made this one, it's unique and good looking, whilst still having the feel of being at Aperture science.
Thought this wasa brilliant, totally confused at the end puzzle and had to resort to the solve after 2 days of pulling my hair out, saw the top glassw chamber, couldnt work it out tho, ah well, all good in the end. If and when portal 2 comes out, i reckon you will have a job!
Yes, that's where many people got stuck. Luckily there are plenty of hints in this thread
I totally look forward to that! If Valve knows how to make money, they should make a second Portal game.
