If anyone here speaks Spanish better than Google or could find more info on the possibility of new Trigun manga I would love you forever.
Native spanish speaker here, translation follows (!!!!):
“During the interview that the entertaining Yasuhiro Nightow gave us during the Madrid event Expomanga 2013, we had the opportunity to chat about his works and his life as a mangaka. One of the topics that surged while talking was, of course, his best work: Trigun.
The author has openly stated his intention to retake said manga in the future, though right now he is centered on the publication Kekkai Sensen, with four years in circulation in the japanese market, he’s commented that the work is not closed completely and, although continuing the work in this series format would be complicated due to lack of time, he would retake Trigun if the opportunity arose, be it in the form of a film or a publication.
Nightow finished Trigun in 2007, after 11 years of publication that yielded two series: Trigun and Trigun Maximum. In 2009 he began to work on Kekkai Sensen, although in 2010 he collaborated to make the film Trigun Badlands Rumble which continued the animated series. In reality, Kekkai Sensen has 6 volumes in the market, with the last one on sale on december 2013 and, according to what the author has told us, he has no plans on finishing the work in the near future. You will be able to read the interview which we conducted across the space of the week. The work (Translator Note: Trigun, presumably) counts with an homonimous television series, directed by Satoshi Nimura and produced by studio MADHOUSE, whose opening took place in september 1998. In april 2010 the film Trigun: Badlands Rumble succeeded the series, with the return of Nishimura and MADHOUSE as director and animation studio, respectively.
In Spain, Trigun was edited for the first time in 1998, with the comic book format by Norma Editorial. With 4 volumes of the original series were split into 7 parts reworked to read in the western format. In march 2005, Ediciones Glenat (today known as EDT) started to publish it as a total of two volumes. Trigun Maximum began to be edited two months later, in may 2005, and collected a total of 14 volumes that saw and end in march 2009. EDT announced in august 2012 its intention to pick up Trigun as a single cumulative volume.
The anime and the film have been edited in Spain by Select Vision.
