Well I think if they release something this year at least around mid-year and the end of the year we will probably already be running backups and have a custom OS...
I don't think TX would sell a chip 4 homebrew... It will surely fully hack\glitch the console... And we all know after that point everyday a new thing appears online and doesn't take much time to get a backup loader, cheats, custom OS, apps.......
Ps: problem is if TX never release anything or gets like gateway, it will take a huge amount of time to get backups then since the exploit Devs are all against piracy, I'm sure they will do everything they can to just give access to homebrew and make it a lot difficult to run backups on their exploits.
