For the next 6 months or more, students will have 4 versions of the GMAT from which to choose:
classic GMAT, GMAT online, GMAT Focus, and GMAT Focus online!

Of course, this also confirms that
there will be a GMAT Focus online version.
Does this also mean that the online version of the GMAT Focus will provide the promised (and free, with the cost of the exam) "expanded score report"—unlike the current, "classic" GMAT online, which offers no
ESR option? Time will tell; this appears to be the case, but GMAC has not yet confirmed it explicitly.
bb, like you, I tried to sign up for the classic GMAT, and the last available test date was still the end of February:
February 29, 2024 to be exact. However, I'm not sure how much this means, because this is also the last date that I can sign up for the GMAT Focus...and it happens to be exactly 6 months from today.
Yesterday you wrote that your last available date to take the classic GMAT was 2/28. This could indicate that the Pearson Vue / Examity registration systems simply don't allow test-takers to sign up for tests further than 6 months in the future. Thus, although
we now can confirm that the GMAT Focus officially starts on or around 11/8/23,
we still cannot confirm exactly when the classic GMAT will end.
