HSPA+ vs LTE, Do you think Google will unveil a refreshed Nexus line at Google I/O?

From the brief research I've done, it seems like HSPA+ just doesn't cut it when it comes down to true LTE. I have a particularly strong desire to purchase a Nexus 7 at the moment, but I'm putting that on the back burner until Google I/O as a precaution. I'm hoping they will refresh the lineup and give their flagship devices some appropriate technology.

What do you think?
