But isnt strange that they just found .wallet and .info files.? NO .key or any wallet backup.

Other than the partial ones, I assume they'll fix the repairable ones themselves?
I dont know about this , i think they dont guarantee that the files are in good condition.

What i think these might be wallets that i created after reinstalling multibit and i deleted them just because i didnt needed those, but im not sure because they dont have the timestamp date or the real name so... idk its like gambling  :S
