Let's do a little math.
The first 744 demo units arrived to vendors in the very beginning of September 2004. I make the call that 744 units are just about now reaching ordinary people out there.
So that gives us a preliminary street date for the 722, July 2005.
Some may argue that a lot of groundwork has been done on the 744 and subsequently the 722 should have a quicker road to full production. Well that would probably be true if there were no other factors. But with a HUGE amount of backordered 744 units to be produced by the actual prouction pipeline (not the R&D + marketing pipeline that has now brought the 722 demo out) I suspect that not only will we not see the 722 until July, we'll probably have to wait until autumn.
I'd hope to be proven wrong of course, but I very much doubt it.
Btw, great call to end the old thread. I was trying to find the date when vendors got their 744 demos and it was a royal PITA to navigate. May I suggest a max page count that is even shorter for future grooming? I think 60% of what the old monster reached is max size for reasonable browsing. Anyway, great work.
