Many believe that it's because the Journal won't be out in time, but it's getting quite close. If that weren't the case they'd have pulled his presentation some time ago. I still believe that NWBO is a steal at these prices and once TLD and the Journal is out its price could easily exceed $5. For me, even with the shares I've added at over $1 a price just over $5 will represent a ten banger and give me about a million dollar position in the stock. $25 to $50 is very possible in the next 2 years.
I should also note that in the U.K. where with the expansion of Sawston's facility and it's approval, Dr. Ashkan is currently able to provide DCVax-L under compassionate use for virtually all solid cancers, not just GBM, for roughly 50 patients a month. It's expensive, but I believe he'll be getting substantial business while it's going through the approval process, which is likely to happen in the U.K. first.
I should also note that in a recent presentation Dr. Stupp, who championed Optune, has backed off, here's a post that summarizes his current position.

If you're interested, if you follow this link you can find a presentation Stupp made that's over an hour long that essentially indicates long term survival with Optune just isn't there. I believe he's starting to believe in the potential of the vaccine.
