I read everything you said guys... Thank you for your advices..but is still very hard to decide. Read this and looks very interesting:
" Having this top-level ccTLD, country code TLD, essentially gives you that extra boost in the search engines when you are targeting those international countries. That is why, generally speaking, if you are a big brand, big site, and you've got a big budget, I would recommend getting these specific ccTLDs, building up those country presences around those language groups. "
subdomains and subfolders..cand be an idea...but not so valuable like the diferent TLD domains
