The head of Team Ninja forgot that the Ninja Gaiden series started back in 1988 with the release of the arcade version of the original game, which also got NES and multiple consoles and computers of that era.
So, of course, yes. (And I don't know how whoever proofread/translated what I assume was originally Japanese text did not know to make the distinction of writing "
our Ninja Gaiden series", not "
the Ninja Gaiden series", or something like that.) There's a lot of headscratching omissions in this short notice.
That said, it's clearly a "
Gambare!" rallying cry for the current Team Ninja as much as it is a celebration of the "second" NG Trilogy/Saga. I like the NES games better than the Xbox games, but I'm not offended that they're celebrating their heritage.
As far as I know, nobody from the Arcade's Strong Team or any of the Tecmo NES NG crew are around at Tecmo anymore (none even seem to have been involved with this Trilogy) and Itagaki is also long gone, plus Team Ninja has had turnover as it is (and hasn't made a new NG since 2012, disregarding Yaiba.) So making it about this team and these games is at least celebrating something about the series in an otherwise dark time. And this Team Ninja would likely be the only ones who could do it again someday (even though they keep busying themselves with other things,) so IMO it's good for them to get some goodwill going for the Team Ninja take on the franchise.
Team Ninja even remembering that it used to make Ninja Gaiden games is a good thing, whatever wonky wording they use to do it.
