So I saw this post on The Points Guy saying that Caesars and MGM are converting from M-Life to MGM Rewards program this month and they are waiving resort fees if you a Diamond Caesars or Gold MGM tier member.
I checked my Caesar's account and was at Gold tier. 
Caesar's tier system matches Wyndham Diamond tier (thanks to the Barclay's Earner+ Card).
Applied and now waiting for formal approval to Diamond status
Looks like our Vegas trip next month will be at Caesars without resort fees !
That's the only good thing about the "new" program. They absolutely gutted the earning structure.
They rolled it out before the official launch. Booked a room a bit back and there were no fees. MGM also extended my status which was supposed to end last month. This trip will make me Platinum. Need to look into the airline credits. Depending on what qualifies, paired with my Delta reserve companion pass, it could make 2 first class about $180

Have you gotten Diamond status yet? I started the Wyndham to Caesars status match on Feb 24th, and still haven't gotten anything. I've tried their twitter, and 2 different emails. Twitter is the only response so far, but gives me generic answers with no real inquiries.
Travel bloggers have been reporting that Caesar's recently updated their status match criteria to say that they will only match "earned" status.
I'm headed to sin city soon and have been digging up info about Las Vegas.
I've come across this MGM Rewards credit card from FNBO and read about the relationship with Hyatt.
I have the slight status upgrade to Hilton and Marriott from an amex. Have been with Hyatt's loyalty program since 1991 but it was dormant for a long time so nothing but basic status so far.
Anyhow, I read about status matching between MGM and Hyatt here, where the relationship between them is explained.
What occurred to me is that since I am close to 2 years of required gardening for a chase card, I could possibly snag one of the FNBO MGM cards and get the second level MGM status from a no fee card. Not particularly useful to me but... The status match information seems to imply that Hyatt will also match MGM Rewards in the following statement. (full info linked above)
EG: "MGM Rewards members are also eligible to opt-in for a matched World of Hyatt tier based on their earned Tier Status in MGM Rewards"
Maybe I am reading it wrong?
Does anyone know if the status tier matching is in fact either way?
..and status granted by a credit card is suitable for status matching?

I could be reading this wrong, but I interpret that statement to mean that only status earned through stays would be eligible for match.
Yes, "earned" stood out to me also.
IIRC, some card based status is considered earned... at least with certain fee based cards.
Aside from 'earned' being a little vague thus far with the context of a card granted status boost, MGM and Hyatt focus mainly on the Hyatt to MGM status matching. Hyatt doesn't appear to mention inbound status matching anywhere, where MGM mentions vaguely.
Unless I can uncover something more concrete in the T&C I guess that a phone call may provide more clarity.
