UPDATE 25/4/14 08.10am: Xbox boss Phil Spencer has now confirmed that game saves from Minecraft: Xbox 360 Edition will be transferrable to the upcoming Xbox One version.
The news comes just 24 hours after Mojang confirmed a similar system would be in place on PS3 and PS4.
After months of teaming up with Mojang, we can confirm that Minecraft X360 Edition will save transfer to Xbox One Edition...more news soon!— Phil Spencer (@XboxP3) April 25, 2014
ORIGINAL STORY 24/4/14 11.10am: Minecraft: PlayStation 3 Edition worlds will be transferrable to the game's upcoming PlayStation 4 version, developer Mojang has stated.
That's "the plan", anyway, Mojang's Owen Hill wrote in the comments of his recent post on the EU PlayStation blog.
"The plan is to enable users to transfer from PS3 to PS4," he explained. "We're still working out how it'll work with the Vita version."
Both the PS4 and Vita versions are now expected in "Q2/Q3" - any time from now until September.
Details on possible discounts (or a full Cross-Buy approach) to the game will be announced closer to its release, Hill continued.
"We'll have more news on cross-buy/upgrade options soon! I understand that the wait is frustrating, but we don't want to make false promises."
Box art for the game's PlayStation 4 and Vita versions was spotted last week - suggesting a release was actually not too far off. The box design is the same as for the physical PS3 version, which will launch in bricks and mortar shops on 14th May.
As for the game's Xbox One version - we've heard little on that for some time.
Xbox boss Phil Spencer at first stated that Minecraft: Xbox 360 Edition saves couldn't be transferred to Xbox One as it was the game's next-gen version was "a new product" - although he later revised this to state that the company was still "discussing" the option with console developer 4J Studios.
