The three titles that you named have all had 
special licensing difficulties, resulting in a 
longer lag between time of announcement 
and time to the store shelf.  (Utena Black 
Rose is licensed and being worked on right 
now for spring/summer release, and they're 
fighting tooth and nail for the Apocalypse arc).  
The point is not whether the titles are 
available, it's whether a company's already 
grabbed the rights to it--and in most cases, if 
it's popular in Japan right now, it's a matter of 
time before someone announces it here.  

Not only that, some companies don't 
announce they've acquired titles until they're 
ready to start sending out press materials and 
retail solicitations.  Right now there are 
probably dozens of titles out there that are on 
their way, but the company's keeping quiet 
until they're ready to roll.  

Plus, there are lots of titles that it's a fool's 
gamble to assume won't see U.S. release 
anytime soon..   Noir, X TV, 
Raxephon--someone's got these, it's just a 
question of when.  The days of "oh, this'll 
never see U.S. shelves" are over; for that we 
need only to look to Tokyopop's upcoming 
Marmalade Boy release.  

Complicating matters further is the high 
number of coproductions out there.  I 
understand some people are fansubbing the 
new Kenshin OAVs.  These people are 
morons--the show is partly financed by ADV 
and will hit shelves stateside this summer.  
The new FY OAVs, Hand Maid May, and 
Hellsing?  All Pioneer US.  

The fact is, companies don't look at what's 
being fansubbed as a sign of what they're 
going to buy, recent acquisitions of old fansub 
favorites notwithstanding.  And because of 
that, companies don't want to send 
representatives to conventions that are 
screening unofficial versions of titles they're 
set to release.   More and more cons are 
going to show either official English versions 
of shows or just raw Japanese, because 
more and more companies are going to crack 
down on this, regardless of how many fans 
whine "six months, but I want it NOOOOW."   
For a much better indication of the average 
turnaround time and the sheer number of 
titles that are getting picked up, check the URL 
above--and check it weekly, because new 
shows are getting announced that frequently. 

If it's worth seeing, it's worth waiting to see 
done correctly, in a version where the artists 
got paid to do it.
