Hi guys. I'm not here asking if season 4 will be released but i do (for once because i've seen so much crap on the internet.) have information about a short film and maybe (i may have misread) a couple or more OVA's Ishibumi just tweeted this from his official account

New book "high school D × DDX.3 cross-x crisis", 11/19 will be released.  http://www. kadokawa.co.jp/product/321603 000654/   …  Will include a short film depicting the encounter of the Novia and Irina phantom series short minutes, and newly written graduation trip. Thank you! # haremking

Check out his official twitter. I don't know if it's the translaion that's a bit iffy but has he ever referred to anything in the book being a 'Short film'

Still...if it is what i think it is, it may not be season 4 but at least we're getting something, and who knows...they're could be hints for a new season in these next animations just like there was with the s2 ova's

Another question: I'd actually like to purchase the light novels but where should i start from?
