PreCentral has spotted a promotional advertisement with a Palm Pre Plus standing in front of several important smartphones. The theory here is since the Pixi never made it across the Atlantic, the poster depicts the European Pixi Plus (and with it, a release of the European Pre Plus as well). According to Laurent Guyot, who is billed by Engadget as a "French PR" individual, the devices will launch on April 27th on the SFR network.
Here's my take on the matter - if you're standing in front of the Motorola Milestone, Sony Ericsson X10, Nokia X6, and other important smartphones, than you're pretty important and should be taken seriously. It's nothing more than a rumor until the devices launch, but given Palm's determination to bring webOS to the masses, it makes sense to bring the flagship models to Europe.
