ISO support is already in there in a way. Where do you think Dark_AleX got the "Sony NP9660" NO UMD that you see in your Recovery Mode?

I believe Sony intended on making some sort of future games in ISO format on the memory stick using the loader of their's.

Sony isn't releasing the 4.00 firmware for a good while, thats why they released this firmware. They needed to buy more time. The naming theme obviously makes everyone think that its only going to be a little bit more but I really only think this is stalling for them and trying to satisfy people like you. They are going to make 3.97 and 3.99 by the end of this year, but I don't think 4.00 is coming till at least November. Keep dreaming guys, everyone needs a little hope

Well, let's look at the release dates of their last four firmwares for a general idea.

3.80 - December 17, '07
3.90 - January 30, '08
3.93 - March 18, '08
3.95 - April 8, '08

The jumps between them are ~45 days, ~48 days and ~20 days respectively. So on average, there's 38 days between updates. Let's just assume Sony will be sticking to that - it won't be exact, but let's just say it's close enough. There are four possible updates between now and the 4.00 release - 3.96, 3.97, 3.98 and 3.99. Assuming Sony won't leapfrog over any of those, 3.99 will be released in 152 days - approximately 5 months, sometime in September. But I think Sony will ignore at least one, bringing that date back to July/August.

So, let's say the last firmware in the 3.XX series comes out in August. How long will it be before the next major release - 4.00? Let's look at how long it took them to do similar jumps.

1.52 - June 15, '05
2.00 - July 26, '05 (JP), August 24, '05 (NA/EU)
NOTE - 2.00 was the only major release that was released earlier in one region than another. So I'll use the JP date.

Difference - ~41 days (staying roughly in the 38 days I said earlier)

2.82 - October 26, '06
3.00 - November 20, '06

Difference - ~24 days

So, all updates are staggered equally. So therefore, going by my prediction of the last 3.XX series release in August, I predict 4.00 will be released in late August/September.

Nice dorkdork777. I could never figure something like that out. Math and I don't like each other :/

Really nice info. I'm impressed. Like dq9 me and math don't get along either

Thanks! Strangely enough, I'm decent at maths, except when I'm off school. Then, only massive amounts of pasta can bring back my maths ability. It just so happened I'd just eaten a giant portion of spaghetti... hence the maths!

But that's all assuming Sony still has some 3.9X releases to come. If that's not right, we can probably expect 4.00 in a month or less!
