I'd rather they remaster the old Xenoblade or Xenosaga games in the short run, and actually give the next Xenoblade a longer dev cycle.
Well I agree the next Xenoblade having a longer development time than XC2, but if you look at it, when did XCX release? April 29, 2015 (later in other regions in Dec 4, 2015) and XC2 released Dec 1, 2017. That's 2 and a half years. Now if they showed XCX2 at E3 2019, (Jun 12, 2019ish) we are looking at the same time frame from RELEASE of XC2 from XCX, to the ANNOUNCEMENT of XCX2 from the release of XC2. Say it came out Dec 4, 2020 that is still literally a year and a half of extra development time from XC2 to XCX2.
IMO plenty of time for a Xeno game. Xenosaga HD collection would be a cherry on top.
